Procedure

To a solution of (R)-methyl 1-(2-amino-3-methylbutanoyl)-4-(4-chlorophenyl)piperidine-4-carboxylate (396 mg, 1.123 mmol) and benzoyl chloride (0.139 ml, 1.2 mmol) in CH2Cl2 (5 mL) was added N-ethyl-N-isopropylpropan-2-amine (0.401 mL, 2.3 mmol). The mixture was stirred for 1 h at rt. The reaction was quenched with NaHCO3 (aq), extracted with dichloromethane, dried over Na2SO4 and concentrated. The residue was purified via column chromatography (20% EtOAc/heptane) to give (R)-methyl 1-(2-benzamido-3-methylbutanoyl)-4-(4-chlorophenyl)piperidine-4-carboxylate (467 mg, 91% yield) as a yellow solid.
