N-Ethylbenzylamine (0.56 mL, 3.8 mmol) and diisopropylethylamine (1 mL, 5.7 mmol) were combined in CH2Cl2 (12 mL) and cooled to 0° C. Phosgene (20% in toluene; 2.4 mL, 4.6 mmol) was added, and the reaction was stirred overnight at room temperature. The mixture was concentrated, and the residue was dissolved in Et2O and washed twice with H2O. The organic layer was dried, filtered, and concentrated to give the title compound.
