MsCl (6.5 mL, 84 mmol) was added slowly to a solution of Et3N (16.0 mL, 114 mmol) and (3-hydroxy-propyl)-carbamic acid tert-butyl ester (13.4 g, 76.5 mmol) in CH2Cl2 (200 mL) at 0° C. (bath temp). The reaction mixture was stirred at rt for 2 h and then quenched with H2O (100 mL). The aqueous layer was extracted with CH2Cl2 and the organic fractions were then dried (MgSO4) and concentrated in vacuo. The title compound was isolated as a colorless oil: yield 18.9 g (98%).
