Water → 3-(3-Chlorophenylsulfonyloxy)-5-methylphenol

Participants

Reaction Steps

5 Orcinol monohydrate (1.42 g, 10 mmol) and 3-chlorobenzenesulfonyl chloride (2.43 g, 11 mmol) were mixed in saturated NaHCO3 (30 mmL and diethyl ether (30 mL). The biphasic mixture was stirred vigorously at room temperature for 2 days. After adding water (50 mL) to the mixture, the mixture was extracted with ethyl acetate (3×50 mL). The organic phase was then washed with brine (2×50 mL) and dried over Na2SO4. The solvent was removed in vacuo and the residue was purified by flash column chromatography (2% ethyl acetate in methylene chloride) to give the title compound as a pale-yellow liquid (2.08 g, 69% ). 1H-NMR (300 MHz, CDCl3) δ 2.24 (s, 3H), 5.32 (s, 1H), 6.33 (t, 1H, J=2.2 Hz), 6.40 (s, 1H), 6.57 (s, 1H), 7.48 (t, 1H, J=8.0 Hz), 7.65 (m, 1H), 7.73 (m, 1H), and 7.86 (t, 1H, J=1.8 Hz).
