The invention relates to quinazoline derivatives of formula (1) wherein m is an integer from 1 to 2; Rrepresents hydrogen, hydroxy, halogeno, nitro, trifluoromethyl, cyano, Calkyl, Calkoxy, Calkylthio, or &#x2014;NRR(wherein Rand R, which may be the same or different, each represents hydrogen or Calkyl); Rrepresents hydrogen, hydroxy, halogeno, methoxy, amino or nitro; Rrepresents hydroxy, halogeno, Calkyl, Calkoxy, Calkanoyloxy, trifluoromethyl, cyano, amino or nitro; Xrepresents &#x2014;O&#x2014;, &#x2014;CH&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014;, &#x2014;SO&#x2014;, &#x2014;NRCO&#x2014;, &#x2014;CONR&#x2014;, &#x2014;SONR&#x2014;, &#x2014;NRSO&#x2014; or &#x2014;NR&#x2014; (wherein R, R, R, Rand Reach independently represents hydrogen, Calkyl or CalkoxyCalkyl); Rrepresents an optionally substituted 5 or 6 membered saturated carbocyclic or heterocyclic group or a group which is alkenyl, alkynyl or optionally substituted alkyl, which alkyl group may contain a heteroatom linking group, which alkenyl, alkynyl or alkyl group may carry a terminal optionally substituted group selected from alkyl and a 5 or 6 membered saturated carbocyclic or heterocyclic group, and salts thereof; processes for their preparation, pharmaceutical compositions containing a compound of formula (I) or a pharmaceutically acceptable salt thereof as active ingredient. The compounds of formula (I) and pharmaceutically acceptable salts thereof inhibit the effects of VEGF, a property of value in the treatment of a number of disease states including cancer and rheumatoid arthritis.

The invention relates to quinazoline derivatives of formula (I) wherein m is an integer from 1 to 2; Rrepresents hydrogen, hydroxy, halogeno, nitro, trifluoromethyl, cyano, Calkyl, Calkoxy, Calkylthio, or &#x2014;NRR(wherein Rand R, which may be the same or different, each represents hydrogen or Calkyl); Rrepresents hydrogen, hydroxy, halogeno, methoxy, amino or nitro; Rrepresents hydroxy, halogeno, Calkyl, Calkoxy, Calkanoyloxy, trifluoromethyl, cyano, amino or nitro; Xrepresents &#x2014;O&#x2014;, &#x2014;CH&#x2014;, &#x2014;S&#x2014;, &#x2014;SO&#x2014;, &#x2014;SO&#x2014;, &#x2014;NRCO&#x2014;, &#x2014;CONR&#x2014;, &#x2014;SONR&#x2014;, &#x2014;NRSO&#x2014; or &#x2014;NR&#x2014; (wherein R, R, R, Rand Reach independently represents hydrogen, Calkyl or CalkoxyCalkyl); Rrepresents an optionally substituted 5 or 6 membered saturated carbocyclic or heterocyclic group or a group which is alkenyl, alkynyl or optionally substituted alkyl, which alkyl group may contain a heteroatom linking group, which alkenyl, alkynyl or alkyl group may carry a terminal optionally substituted group selected from alkyl and a 5 or 6 membered saturated carbocyclic or heterocyclic group, and salts thereof; processes for their preparation, pharmaceutical compostions containing a compound of formula (I) or a pharmaceutically acceptable salt thereof as active ingredient. The compounds of formula (I) and the pharmaceutically acceptable salts thereof inhibit the effects of VEGP, a property of value in the treatment of a number of disease states including cancer and rheumatoid arthritis.

A method is disclosed of identifying parent ions by matching daughter ions found to be produced at substantially the same time that the parent ions elute from a mixture. Ions emitted from an ion source are incident upon a collision cell which alternately and repeatedly switches between a first mode wherein the ions are substantially fragmented to produce daughter ions and a second mode wherein the ions are not substantially fragmented. Mass spectra are taken in both modes, and at the end of an experimental run parent and daughter ions are recognized by comparing the mass spectra obtained in the two different modes. Daughter ions are matched to particular parent ions on the basis of the closeness of fit of their elution times, and this enables parent ions to then be identified.
