Procedure

To a solution of the amine from Step D (754 mg, 1.93 mmol) and triethylamine (0.403 mL, 2.89 mmol) in 5 mL of dichloromethane at 0° C. was added benzylchloroformate (0.303 mL, 2.12 mmol). After 2 hours, the solution was poured into EtOAc and sat NH4Cl solution, and the organic layer was washed with sat. NaHCO3 soln. and brine, dried (Na2SO4), filtered, and concentrated in vacuo to provide the crude product which was purified by silica gel chromatography (30-40% EtOAc/hexane) to obtain the titled compound as a white foam.
