실험 절차

Benzoyl chloride (3.51 g, 25 mmol) was added dropwise to a solution of 2-chloro-5-methylphenol (3.92 g, 27.5 mmol) and triethylamine (5 mL) in dichloromethane (100 mL), The mixture was stirred for 18 hours at room temperature and concentrated under reduced pressure. Diethylether (200 mL) and water (100 mL) were added. The organic layer was separated and extracted with 2N NaOH (2×100 mL) and brine (50 mL), dried over sodium sulphate and concentrated under reduced pressure. The resulting colourless oil solidified in the freezer. Yield: 5.82 g (94%). 1H-NMR (400 MHz, CDCl3) δ 2.38 (s, 3H, —CH3), 7.05 (d, J=8.2 Hz, 1H), 7.11 (s, 1H), 7.36 (d, J=8.2 Hz, 1H), 7.51-7.56 (m, 2H), 7.64-7.7.70 (m, 1H), 8.22-8.28 (m, 2H). 13C-NMR (100 MHz, CDCl3) δ=21.41, 123.97, 124.58, 128.07, 128.85, 129.15, 130.07, 130.55, 134.01, 138.38, 146.98, 164.51.
