Reaction Steps
To a stirred solution of 4-chloro-3-methoxybenzeneamine (4.7 g, 29.6 mmol) in methylene chloride (100 mL) at ˜0° C. was slowly added 2,4dibromobutyryl chloride (5.1 mL, 39 mmol). After the addition, the reaction mixture was stirred for ˜5 minutes and triethylamine (24.7 mL, 178 mmol) was then added. The resulting reaction mixture was allowed to warm up to room temperature and stirred at room temperature for 5 days. Water (˜100 mL) was then added to the reaction mixture. The organic layer was separated, dried over MgSO4 and concentrated. The residue was purified by column chromatography (silica gel, ˜33% ethyl acetate/˜67% hexanes) to give the title compound as a yellow solid (3.9 g) melting at 113–115° C.
