YieldReaction ConditionsOperation in experiment
4.8 g To a solution of <strong>[222978-01-0](4-bromo-3-fluorophenyl)methanol</strong> (5.0 g, 24 mmol) in tetrahydrofuran (150 mL) at 0 C was added sodium hydride (1.4 g, 34 mmol). The reaction was stirred at this temperature for 10 min, and then methyl iodide (4.1 g, 29 mmol) was added. The reaction was allowed to warm from 0 C to 20 C over 3 hours, then quenched with saturated aqueous ammonium chloride (50 mL) and extracted with ethyl acetate (3 chi 100 mL). The combined organic layers were washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by silica gel chromatography [petroleum ether: ethyl acetate = 30: 1] to give compound B- 308 (4.8 g, 90% yield) as an orange oil. TLC [petroleum ether: ethyl acetate = 10: 1]: Rf=0.5; - NMR (CDC13, 400 MHz): delta 7.53 (t, J=8.0 Hz, 1H), 7.14 (d, J=9.2 Hz, 1H), 7.01 (d, J=8.0 Hz, 1H), 4.43 (s, 2H), 3.42 (s, 3H).
