1-bromo-2-propan-2-ylsulfanylbenzene

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: To 21A (0.7 g, 3.0 mmol) in methanol (5 mL) was added oxone®8 (5.6 g, 9.0 mmol) in water (5 mL). The reaction was stirred at rt for 4 h. The reaction was quenched with 5% NaHSO3 and then neutralized with 1 M NaOH. The organic solvent was evaporated and the aqueous layer was extracted with dichloromethane (3×). The combined extracts were washed with brine and dried over sodium sulfate. The solvent was removed to give 0.53 g of product 21B (67% yield). 1H NMR (400 MHz, Methanol-d4) δ ppm 1.26 (d, J=6.85 Hz, 6H) 3.80-4.00 (m, 1H) 7.45-7.68 (m, 2H) 7.87 (dd, J=7.46, 1.59 Hz, 1H) 8.10 (dd, J=7.34, 2.20 Hz, 1H).
