Methanol → Methyl 4-tetrahydrofuran-3-ylsulfonylbenzoate

참여 물질

반응 단계

Methyl 4-tetrahydrofuran-3-ylsulfanylbenzoate (1.01 g, 4.24 mmol) was dissolved in methanol (25 mL), followed by the addition of water (2.5 mL), and Oxone (2.61 g, 4.24 mmol). The reaction mixture was stirred at room temperature for 24 hours. An additional 0.1 eq of Oxone (0.26 g) was added and the reaction mixture was stirred for 2 hours, then filtered and the solvent was concentrated in vacuo. The resulting residue was dissolved in dichloromethane (30 mL) and washed with water (2×25 mL). The organic layer was dried over sodium sulfate, filtered and concentrated in vacuo to yield methyl 4-tetrahydrofuran-3-ylsulfonylbenzoate (1.07 g, 93%) as a yellow solid. ESI-MS m/z calc. 270.1. found 271.3 (M+1)+; Retention time: 1.02 minutes (3 min run).
