실험 절차

Potassium carbonate (1.2 g, 8.9 mmol) was added to a mixture of methyl 4-sulfanylbenzoate (1.0 g, 6.0 mmol), 1-bromo-2-methyl-propane (1.2 g, 970 μL, 8.9 mmol), and DMF (10 mL) at room temperature. The reaction mixture was allowed to stir for 4 hours and the resulting solid was removed by filtration. The filtrate were partitioned between ethyl acetate (100 mL) and water (100 mL). The layers were separated and the organic layer was washed with brine solution, then dried over sodium sulfate, filtered and concentrated in vacuo to give methyl 4-isobutylsulfanylbenzoate (1.1 g, 83%) as a clear oil. ESI-MS m/z calc. 242.0. Found 243.2 (M+1)+; Retention time: 1.73 minutes (3 min run). 1H NMR (400 MHz, CDCl3) δ 8.30 (d, J=8.3 Hz, 2H), 8.05 (d, J=8.3 Hz, 2H), 3.03 (d, J=6.5 Hz, 2H), 2.27 (dt, J=13.3, 6.6 Hz, 1H), 1.08 (d, J=6.7 Hz, 6H).
