To a stirring mixture of 4-(heptyloxy)benzothioamide (1.30 g, 5.17 mmol) in isopropanol (20 mL) was added 2-bromo-1-(4-bromophenyl)ethanone (1.44 g, 5.17 mmol). The precipitate was collected by filtration and washed with EtOH (2×5 mL). The filter cake was slurried with NaHCO3 (2×20 mL), water (2×20 mL) then EtOH (2×5 mL) and dried to afford 926 mg (41%) of 4-(4-bromophenyl)-2-(4-(heptyloxy)phenyl)thiazole as a pale yellow powder. LCMS-ESI (m/z) calculated for C22H24BrNOS: 429.1. found 430.0 [M+H]+, tR=3.41 min. (Method 4).
