Reaction Steps

To a solution of (R)-tert-butyl 3-(6-fluoro-3′-methylbiphenylcarbonyl)piperidine-1-carboxylate (3.5 g, 6.29 mmol) in MeOH (50 mL) was added NaBH4 (0.95 g, 25 mmol) in portions at rt. After addition, the mixture was stirred for 2 h. Tlc showed the starting material had disappeared. The solvent was removed in vacuo to leave a residue which was partitioned between water and EtOAc. The organic layer was washed with H2O and brine, dried over Na2SO4 and evaporated to give (3R)-tert-butyl 3-((6-fluoro-3′-methylbiphenyl-2-yl)(hydroxy)methyl)piperidine-1-carboxylate (3.5 g, 100%), which was used in the next step without purification.
