Reaction Steps

A mixture of 5-iodo-2-methylbenzoic acid (760 mg, 2.9 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (670 mg, 3.5 mmol), 4-dimethylaminopyridine (425 mg, 3.5 mmol), and t-butanol (1.07 g, 14.5 mmol) in dichloromethane (10 ml) was stirred at room temperature overnight. The reaction mixture was diluted with ethyl acetate (25 ml) and washed with 5% NaHCO3, 1M HCl, water and, brine. The organic phase was dried and evaporated to give a pale yellow solid 600 mg 65%.
