Reaction Steps

To a suspension of 4-(3-chloro-phenyl)-6-(5-chloro-thiophene-2-carbonyl)-1-methyl-1H-quinolin-2-one (58 mg, 0.154 mmol) in MeOH (1 ml) was added sodium borohydride as solid (NaBH4, 7 mg, 0.185 mmol) at 0° C. The reaction mixture was stirred at 0° C. for one hour after which time it was partitioned between chloroform and water. The organic layer was washed with brine, dried over MgSO4 and concentrated under vacuum to give an off-white solid (49 mg, 78.5% yield).
