Ethyl Bromide → HCID 57790784, compound

Participants

Reaction Steps

To a mixture of t-butyl (2-hydroxy-1-methylethyl)carbamate (2.89 g) and tetrabutylammonium hydrogen sulfate (560 mg, 0.1 equiv) in toluene (33 mL) and 50% aqueous sodium hydroxide solution (6.6 mL, 5 equiv) was added ethyl bromide (1.85 mL, 1.5 equiv) at room temperature. The mixture was stirred at room temperature for 4 days. The reaction mixture was partitioned between water and ethyl ether. The organic layer was washed with water and brine, dried over sodium sulfate, and concentrated in vacuo to provide the crude product, which was purified by silica chromatography (9:1 to 75:25 hexanes:ethyl acetate (EtOAc)) to provide the title compound (2.00 g, 60% yield).
