실험 절차

A mixture of 4-bromo-2,6-diethyl-N-quinolin-8-yl-benzamide (2.9 g, 7.6 mmol) in 40% sulphuric acid (15 ml) is heated at 120° C. for 16 h. After completion, the reaction mixture is extracted with ether (2×100 ml) and the combined organic layers are dried over sodium sulfate and concentrated to obtain 4-bromo-2,6-diethyl-benzoic acid (1.1 g, 4.28 mmol, 56%).
