Dichloromethane → Benzyl N-(3-hydroxypropyl)carbamate

Participants

Reaction Steps

To a mixture of 3-aminopropan-1-ol (5.0 g, 67 mmol), Na2CO3 (8.8 g, 83 mmol) in THF (40 mL) and H2O (130 mL) at 0° C. was added Cbz-Cl (14.8 g, 87 mmol). The reaction mixture was stirred (RT, 1 h). Water (500 mL) and CH2Cl2 (500 mL) were added, and the layers were separated. The organic layer was dried over MgSO4 and concentrated under reduced pressure. The residue was purified by silica gel chromatography (PE:EtOAc, 5:1) to afford benzyl 3-hydroxypropylcarbamate as a white solid (12.6 g, 90.5%).
