The invention relates to a process for preparation of a compound of formula (I): Ris selected from Calkyl, Calkenyl, and Calkynyl;which comprises:(i) reaction with fluoride, suitably [F]fluoride, of a corresponding compound of formula (II): wherein Ris selected from hydrogen, Calkyl, Chaloalkyl, Caryl, Carylalkyl, &#x2014;(CHCHO)&#x2014;CHwherein q is an integer of from 1 to 10;Ris as defined for the compound of formula (I); andRis a leaving group. Certain novel precursors of formula (II) and radiopharmaceutical kits containing such precursors are also claimed.

Fluorination process

The invention relates to a process for preparation of a compound of formula (I): Ris selected from Calkyl, Calkenyl, and Calkynyl; which comprises: (i) reaction with fluoride, suitably [F]fluoride, of a corresponding compound of formula (II): wherein Ris selected from hydrogen, Calkyl, Chaloalkyl, Caryl, Carylalkyl, &#x2014;(CHCHO)&#x2014;CHwherein q is an integer of from 1 to 10; Ris as defined for the compound of formula (I); and Ris a leaving group. Certain novel precursors of formula (II) and radiopharmaceutical kits containing such precursors are also claimed. 

Fluorination process of anilide derivatives and benzothiazole fluorinate derivatives as in vivo imaging agents

A compound that has affinity with amyloid, exhibits sufficiently rapid clearance from normal tissues, and is suppressed in toxicity such as mutagenicity is provided, which is represented by the following formula (1): or a salt thereof,wherein Ris a group selected from hydrogen, hydroxyl group, carboxyl group, sulfate group, amino group, nitro group, cyano group, an alkyl substituent with one to 4 carbon atoms or an alkoxy substituent with one to 4 carbon atoms; Ris a radioactive halogen substituent; and m is an integer of 0 to 2, and a low-toxic diagnostic agent for Alzheimer's disease comprising a compound represented by the above formula or a salt thereof is also provided.

Compound having affinity for amyloid

The invention provides compounds of formula (I) or a salt thereof, radiolabelled versions thereof, and their use in the diagnosis or in vivo imaging of Amyloid-associated diseases such as Alzheimer's disease
