Participants

Reaction Steps

A mixture of bromomethylketone (b) (2.07 g, 9 mmol), 1,1-dimethylethyl (3-amino-3-thioxopropyl)carbamate (1.84 g, 9 mmol) and sodium bicarbonate (0.76 g, 9 mmol) in ethanol (120 mL) was heated to reflux for 1 hour under argon. The mixture was evaporated and the residue partitioned between ethyl acetate and aqueous sodium bicarbonate solution. The organic extract was washed with brine, dried and evaporated. The residue was chromatographed on silica eluting with a gradient of 0–50% ethyl acetate in dichloromethane affording a yellow solid (0.93 g, 26%).
