ethyl N-(2-bromophenyl)carbamate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2.44 g of the 2-bromo-1-ethoxycarbonylaminobenzene was added to a solution containing 680 mg of sodium ethoxide, 170 mg of cupric chloride dihydrate, and 156 mg of 2,2'-bipyridine in 40 ml of methanol, and the mixture was heated under reflux for 1.5 hours. After the temperature was brought to room temperature, ethyl acetate was added thereto, and the resulting mixture was washed with water and dried over Glauber's salt. The solvent was distilled off, and the obtained crude crystals were recrystallized from a n-hexane/ethyl acetate solvent mixture, to obtain 1.75 g (yield: 84%) of the desired compound. The spectrum data of the compound was in agreement with the spectrum data of the separately synthesized reference compound. the mixture was heated under reflux for 1.5 hours was brought to room temperature the resulting mixture was washed with water dried over Glauber's salt The solvent was distilled off the obtained crude crystals were recrystallized from a n-hexane/ethyl acetate solvent mixture
