Process for preparing 1-(6-methylpyridin-3-yl)-2-[4-(methylsulfonyl)phenyl]ethanone

摘要

A five-step process for preparing 1-(6-methylpyridin-3-yl)-2-[(4-(methylsulphonyl)phenyl]-ethanone of the formula starting from 4-(methylthio)benzyl alcohol is described. The compound of the formula I is an intermediate for preparing COX-2 inhibitors, pharmaceutically active compounds having analgesic and antiinflammatory action.
