Procedure
Ethylamine (1.3 mL, 20.0 mmol) and diisopropylethylamine (7 mL, 40.0 mmol) were combined in CH2Cl2 (200 mL) and cooled to 0° C. Benzyl chloroformate (2.86 mL, 20.0 mmol) was added dropwise, and the reaction was stirred at 0° C. for 30 minutes. Once no starting material was seen by analytical tlc, the mixture was warmed to room temperature and washed with H2O, 0.1N aqueous HCl, and H2O, and then dried and concentrated to give the title compound.
