実験手順

A solution of ethyl isothiocyanate (1-1) (652 mg, 7.5 mmol) and aniline (1-2) (465 mg, 5.0 mmol) in acetonitrile (5 mL) is heated to 80° C. for 14 hours. After cooling to room temperature, the mixture is poured into water (50 mL) and extracted with ethyl acetate (EtOAc) (3×50 mL). The combined organic layers are washed with brine and dried using MgSO4. The drying agents are removed by filtration and the solvent is removed under vacuum. The resulting residue is then purified by flash column chromatography (silica gel, EtOAc/hexane, 0%˜40%) to provide 1-ethyl-3-phenylthiourea (1-3) as a white powder. HPLC-MS calculated for C9H12N2S (M+H+) 181.1. found 181.1.
