Participants

Reaction Steps

A solution of o-bromobenzoic acid (1 g), N, N'-dicyclohexyl carbodiimide (1.129 g), t-butanol (405 mg) and 4-dimethylaminopyridine (61 mg) in dry ether (20 ml) was stirred at room temperature for 18 h. The resulting precipitate was filtered off and the filtrate evaporated to give a colourless solid which was triturated under petroleum ether (40°-600°) (20 ml) and filtered. The filtrate was evaporated to give a pale yellow oil (0,994 g). b.p. 80°-84°/0.35 mmHg.
