A mixture of 1-[(3′-acetyl-5′-chloro-3-fluoro-2′-methoxy-6′-methylbiphenyl-4-yl)carbonyl]azetidine-3-carbonitrile (25 mg, 0.062 mmol), ammonium acetate (48 mg, 0.62 mmol) and sodium cyanoborohydride (8 mg, 0.1 mmol) in methanol (0.2 mL) and acetonitrile (0.2 mL) was heated at 65° C. overnight in a sealed tube. The mixture was cooled to room temperature, quenched with saturated sodium bicarbonate and extracted with dichloromethane. The combined extracts were dried over magnesium sulfate, filtered and concentrated to dryness. The resulting crude product was used directly in next step (21 mg, 84%). LCMS calculated for C21H19ClFN2O2 (M−NH2)+: m/z=385.1. found: 385.1.
