Participants

Reaction Steps

Benzyl 3-hydroxypropylcarbamate (15 g, 72 mmol) was treated with imidazole (10 g, 146.9 mmol) and TBSCl (12 g, 79.6 mmol) in DMF (10 ml) at 0° C. After warming up the reaction mixture to room temperature, it was stirred for 30 minutes. The resulting solution was quenched with water (50 ml), and then extracted with diethyl ether (50 ml×2) twice. After evaporation of volatile material under reduced pressure, the residue was purified with silica gel column chromatography (EtOAc:Hx=1:10) to afford title compound (23 g, 98%) as colorless oil.
