Procedure

A mixture of 4-(4-chlorophenyl)-3,3-dimethylpiperidine, isomer A (1.1 g, 4.92 mmol), Boc-D-Val-OH (1.068 g, 4.92 mmol), HOBT (1.656 g, 10.82 mmol), and triethylamine (3.43 mL, 24.58 mmol) in methylene chloride (20 mL) was treated with EDC (2.073 g, 10.82 mmol), and the reaction was allowed to stir overnight at room temperature. The mixture was concentrated in-vacuo, and the residue was taken up in ethyl acetate. The organic phase was washed 3× with 1M NaOH, 3× with 1M HCl, and once with brine, dried over sodium sulfate, and concentrated in-vacuo to yield the title compound (2.25 g). MS (ESI+)=423.5, (M+H)+.
