Abstract:
The present invention provides a process for the manufacture of a compound of formula VIIIa and salts forms of VIIIa where R c  is an aryl sulfonic acid

Claim (Index 15):
A process for the preparation of 4-(2-(methylsulfonyl)pyrimidin-4-yl)pyridin-2(1H)-one (VII) comprising the steps of: (a) contacting 2-fluoro-4-iodopyridine with a metallating agent in an aprotic organic solvent to afford an organomagnesium compound, which is reacted with 4-chloro-2(methylthio)pyrimidine in the presence of a palladium catalyst to afford 4-(2-fluoropyridin-4-yl)-2-(methylthio)pyrimidine (X); (b) treating X with potassium tert-butoxide in THF and subsequently with an aqueous acid to afford 4-(2-(methylsulfonyl)pyrimidin-4-yl)pyridin-2(1H)-one (VII).
