Ethyl Bromide → HCID 58951694, compound

Temperature

0 °C

A solution of 2-(3-chlorophenyl)acetonitrile (10.00 g, 66 mmol) and ethyl bromide (4.9 mL, 66 mmol) in DMSO (25 mL) was added dropwise to a stirred solution of NaH (60% dispersion in mineral oil (2.6 g, 66 mmol)) in DMSO (75 mL) at 0° C. under a nitrogen atmosphere. The reaction mixture was stirred for 30 minutes at 0° C. and then brought to room temperature and stirred for 23 hours. The reaction mixture was carefully quenched with water, and was then diluted with EtOAc. The organic layer was separated, washed with water (2×) and brine, dried (MgSO4), and concentrated in vacuo to give the crude product as an orange oil. The crude oil was purified by silica flash chromatography (0-5% EtOAc/hexane) to give the desired compound as a colorless oil (4.69 g).
