Triethylamine → Benzyl N-(3-hydroxypropyl)carbamate

Participants

Reaction Steps

3-Aminopropan-1-ol (10 g, 133 mmol) was dissolved in methylene chloride (100 ml) at 0° C. Triethylamine (9 ml, 65 mmol) and CbzCl (10 ml, 66.8 mmol) were added slowly to the solution at 0° C. and warmed to room temperature. The reaction mixture was stirred for 1 hour at room temperature, and then diethyl ether (100 ml) and water (50 ml) were poured into the resulting solution. With diethyl ether normal work-up was taken, dried with magnesium sulfate. After evaporation the volatile material, the residue was purified with normal phase preparative column to produce title compound (15 g, 95%) as colorless oil.
