Reaction Conditions

Reaction Steps

A suspension of (6′-chloro-5′-cyano-4′-difluoromethyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-yl)-methyl-carbamic acid tert-butyl ester (1.1 g, 2.74 mmol) potassium carbonate (1.9 g, 13.7 mmol) in DMF (15 mL) was treated with 2-mercaptoacetamide (solution of 1 g, 11 mmol in 10 mL of methanol), and the reaction mixture was heated in a sealed tube at 80° C. overnight. The reaction mixture was then cooled to room temperature and filtered. The filtrate was treated with water (50 mL) and the resulting precipitate was collected by filtration to provide 1.03 g (82.4%) of [1-(3-amino-2-carbamoyl-4-difluoromethyl-thieno[2,3-b]pyridin-6-yl)-piperidin-4-yl]-methyl-carbamic acid tert-butyl ester as a tan solid.
