Reaction Steps

Treat a solution of chiral 1-cyclohexyl-3-[3,5-dichloro-4′-(2,5-diaza-bicyclo[2.2.1]heptane-2-carbonyl)-biphenyl-4-ylmethyl]-pyrrolidin-2-one (0.096 g, 0.18 mmol) in methanol (3 mL) and acetone (0.105 g, 1.81 mmol) with sodium cyanoborohydride (0.055 g, 0.88 mmol) and then acetic acid (0.057 g, 0.94 mmol). Stir the mixture for 3 hours at room temperature under a nitrogen atmosphere, dilute with ethyl acetate and wash with saturated sodium bicarbonate then water. Dry the organic layer with sodium sulfate and purify the crude product by silica gel chromatography using a gradient of 0 to 10% methanol in dichloromethane to afford 71 mg (68%) of the title compound: MS (m/z): 568 (M+).
