Participants

Reaction Steps

Slurry 4-cyanophenacyl bromide (1.4 g, 6.3 mmol), 2,2,2-trifluoroethyl-thiourea (1.0 g, 6.3 mmol) and sodium bicarbonate (529 mg, 6.3 mmol) in absolute ethanol (30 mL). Stir the mixture at reflux for 1 h under a nitrogen atmosphere. Cool to room temperature and concentrate in vacuo. Partition the residue between DCM (100 mL) and water (20 mL). Dry the organic layer over Na2SO4 and concentrate in vacuo to obtain the desired intermediate (1.7 g, 95%). MS (ES+) m/z: 284 (M+H)+.
