Reaction Steps

To a solution of 4-(7-cyano-1-cyclopentyl-4-methoxy-1H-pyrazolo[4,3-c]pyridin-3-yl)thiophene-2-carboxamide (53.3 mg) in acetonitrile (10 mL) were added sodium iodide (43.5 mg) and chloro(trimethyl)silane (0.147 mL), and the mixture was stirred at 60° C. for 30 min. The reaction mixture was concentrated under reduced pressure, and the residue was washed successively with water and ethyl acetate to give the title compound (50.3 mg).
