Procedure

Thiourea 4 (200 mg, 0.61 mmol, 1 equiv.) was stirred in CH2Cl2 (10 mL) under N2 atmosphere. 6-Bromohexanoyl chloride (195.8 mg, 0.92 mmol, 1.5 equiv.) was added, followed by triethylamine (85 μL, 0.61 mmol, 1 equiv.). The beige suspension was stirred at rt for 1.5 h and diluted with CH2Cl2 (10 mL). The organic solution was washed with 1 M aqueous hydrochloric acid (1×10 mL), 10% aqueous sodium hydroxide (1×50 mL), and saturated brine (1×10 mL). The organic phase was dried over MgSO4 and concentrated in vacuo. The resulting brown foam was purified by flash chromatography on silica (50% ethyl acetate/petroleum ether) to give 6-bromo-hexanoic acid {4-[3-(4-tert-butyl-benzoyl)-thioureido]-phenyl}-amide (166 mg, 55%) as a yellow oil.
