Imidazole → 3-(Tert-butyldiphenylsiloxy)propanol

Participants

Reaction Steps

To a solution of 1,3-propanediol (1.25 g, 16.4 mmol) in N,N-dimethylformamide (50 mL) was added imidazole (2.23 g, 32.8 mmol) and tert-butyldiphenylsilyl chloride (4.97 g, 18.1 mmol). The reaction was stirred for 3 days at room temperature, then was diluted with ethyl acetate and was washed with water and brine. Concentration in vacuo afforded the crude product as a thick colorless oil which was used directly in the next step.
