There is provided processes for preparing Lubiprostone and intermediates thereof. Also provided are compounds, including intermediates for preparing Lubiprostone as well compositions comprising Lubiprostone and other compounds, including intermediates for preparing Lubiprostone and other compounds. (I) 

Methods of making lubiprostone and intermediates thereof

Solid and crystalline forms of tofacitinib hydrochloride and tofacitinib hydrobromide, processes for the preparation thereof and processes for the use thereof in preparing tofacitinib citrate are provided.

Solid forms of tofacitinib salts

Provided is dexlansoprazole propylene glycolate hydrate. Polymorphic forms thereof are also provided. The dexlansoprazole propylene glycolate hydrate maybe such that the propylene glycol component is present in approximately equal proportions of (R) absolute configuration and (S) absolute configuration, or present in predominantly (R) absolute configuration, or predominantly (S) absolute configuration. Salts of dexlansoprazole are also provided. In particular, crystalline dexlansoprazole isopropylammonium salt and crystalline MTBE solvate of dexlansoprazole t-butylammonium salt are provided. Pharmaceutical formulations comprising dexlansoprazole propylene glycolate hydrate are also provided. Furthermore, processes for preparation of dexlansoprazole propylene glycolate hydrate are provided.

Forms of dexlansoprazole and processes for the preparation thereof

A novel process for the preparation of omeprazole and its enantiomers, such as esomeprazole, as well as the preparation of related 2-(2-pyridinylmethyl-sulphinyl)-1H-benzimidazoles, including pantoprazole, lansoprazole and rabeprazole, as recemates or single enantiomers, and their alkali or alkaline salts has been developed. The novel process involves the surprising discovery that protection of the free-base benzimidazole sulfoxide (e.g. omeprazole or esomeprazole), by reaction with an alkyl, aryl or aralkyl chloroformate following oxidation of the corresponding sulfide, eliminates the need for its direct isolation. Subsequent removal of the protecting group with a solution of alkali or alkaline earth alkoxide in a C1-C4 alcohol directly provides the corresponding salt. By eliminating the need to handle the free-base benzimidazole sulfoxide, this advantageous procedure provides increased chemical yields over processes described in the art.

Process for the preparation of esomeprazole and salts thereof

A process is provided for preparing (R)-5-[2-(4-fluorophenyl)-5-(1-methylethyl)-3-phenyl-4-[(phenylamino)carbonyl]-1H-pyrrol-1-yl]-5-hydroxy-3-oxo-1-heptanoic acid, R-substituted ester 9 comprising:
