실험 절차
Following the general procedure for the synthesis of derivatives 6 and 7, a solution of 1-(3-hydroxy-4-methoxyphenyl)thiourea (150 mg, 0.76 mmol) and ethyl 3-bromopyruvate (0.095 mL, 0.76 mmol) in dry DMF (3.0 mL) was heated at 60° C. for 6 h. The title compound was obtained after purification by flash chromatography on silica gel (hexane:EtOAc 6/4) in 63% yield (139 mg).
