To a solution of N-methoxy-N-methylthieno[3,2-c]pyridine-2-carboxamide (D′-2) (11.1 g, 50 mmol) in anhydrous THF (150 mL) was added MeMgBr (3M in ethyl ether, 25 mL, 75 mmol) at 0° C. under N2. The reaction mixture was allowed to warm to the ambient temperature and stirred overnight. Saturated aqueous NH4Cl solution was added to quench the reaction. The resulting mixture was then extracted with EtOAc. The combined organic layers were dried over Na2SO4, filtered, and concentrated to afford the title compound. MS (m/z): 178 (M+1)+.
