Reaction Steps

Dehydrated tert-butanol (0.19 ml, 2.0 mmol), 4-dimethylaminopyridine (81 mg, 0.67 mmol) and EDCI (255 mg, 1.33 mmol) were added to a solution of 4-bromo-3,5-dimethyl-benzoic acid (123 mg, 0.535 mmol) in dichloromethane (1.0 ml) at 0° C., and the mixture was stirred at room temperature for 25 hours. The reaction mixture was diluted with dichloromethane, and the organic layer was washed with water, dried over MgSO4 and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate=100/1→50/1) to give 4-bromo-3,5-dimethyl-benzoic acid tert-butyl ester (106 mg, 70%).
