A mixture of [4-(3-acetyl-5-chloro-2-methoxy-6-methylphenyl)-1H-pyrazol-1-yl]acetonitrile (0.10 g, 0.33 mmol), ammonium acetate (0.254 g, 3.29 mmol) and 1.0 M sodium cyanoborohydride in tetrahydrofuran (0.82 mL, 0.82 mmol) in methanol (0.9 mL) and acetonitrile (0.9 mL) was heated at 65° C. overnight. The mixture was cooled to room temperature, quenched with saturated sodium bicarbonate solution and extracted with dichloromethane. The combined organic layers were dried over MgSO4 and concentrated to give the desired product. LCMS calculated for C15H15ClN3O (M−NH2)+: m/z=288.1. found: 288.0.
