実験手順

A stirred mixture of 4-[(3-bromophenyl)-N-acetylamino]-8-methyl-6-nitro-quinoline-3-carbonitrile (10.6 g, 25 mmol), N-bromosuccinimide (6.68 g, 37.5 mmol), 0.30 g of dibenzoyl peroxide, and 200 ml of carbon tetrachloride was refluxed for 2 h, treated with an additional 0.30 g of dibenzoyl peroxide, and refluxed an additional 2.5 h, cooled, diluted with methylene chloride, and stirred with aqueous sodium bisulfite. The organic layer was separated and washed successively with water, sodium bicarbonate solution, and water. The solution was dried and evaporated to give 15 g of a white foam, NMR (CDCl3) d 5.19 (dd, CH2Br).
