A mixture of 1-{4-chloro-6-[1-(1-ethoxyethyl)-1H-pyrazol-4-yl]-3′-fluoro-5-methylbiphenyl-2-yl}ethanone (37 mg, 0.092 mmol), ammonium acetate (71 mg, 0.92 mmol) and 1.0 M sodium cyanoborohydride in tetrahydrofuran (0.23 mL, 0.23 mmol) in methanol (0.5 mL) and acetonitrile (0.5 mL) was heated at 65° C. overnight. The mixture was cooled to room temperature, quenched with saturated sodium bicarbonate solution, extracted with dichloromethane. The combined organic layers were dried over MgSO4, filtered and concentrated to give the desired product (35 mg). LCMS calculated for C22H26ClFN3O (M+H)+: m/z=402.2. found: 402.2.
