[2-(trifluoromethyl)phenyl]thiourea

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a stirred solution of 2-(trifluoromethyl)phenylthiourea (Menai Organics, 2.36 g, 10.7 mmol), Hunig's base (Aldrich, 1.9 mL, 10.7 mmol) in EtOH (10 mL) was added diethyl bromomalonate (2.0 mL, 10.7 mmol). After 1.5 h at room temperature, the reaction mixture was diluted with EtOAc, washed with saturated NaHCO3 and brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel chromatography. MS: 333 (M+1). washed with saturated NaHCO3 and brine dried over Na2SO4 filtered concentrated in vacuo The crude product was purified by silica gel chromatography
