Imidazole → HCID 10535529, compound

Participants

Reaction Steps

Imidazole (33.6 g, 495 mmol) and tert-butyldimethylsilyl chloride (27.2 g, 180 mmol) were added to a 0° C. solution of 3-hydroxypropanenitrile (10.6 g, 150 mmol) in DMF 50 mL). The mixture was allowed to warm to rt, then was stirred at rt for 12 hrs. The mixture was quenched with water (500 mL), and then extracted with EtOAc (3×). The combined organic layer was dried over Na2SO4 and concentrated. The residue was purified by silica gel column chromatography (gradient elution 0˜5% EtOAc/petroleum ether) to give 3-(tert-butyldimethylsilyloxy) propanenitrile (18 g, 75%) as a colorless oil. 1H NMR (400 MHz, CDCl3): δ 3.74 (t, J=6.0 Hz, 2H), 2.43 (t, J=6.0 Hz, 2H), 0.81 (s, 9H), 0.00 (s, 6H).
