(3-hydroxyphenyl)thiourea

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

Procedure: Following the general procedure for the synthesis of derivatives 6 and 7, a solution of 3-hydroxyphenylthiourea (150 mg, 0.89 mmol) and ethyl 3-bromopyruvate (0.11 mL, 0.89 mmol) in dry DMF (3.6 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 81% yield (189 mg). for the synthesis of derivatives 6 and 7
