Borane;tetrahydrofuran → [1-(4-Bromo-2-methoxyphenyl)cyclobutyl]methanol

Participants

Reaction Steps

To a mixture of 1-(4-bromo-2-methoxyphenyl)cyclobutanecarboxylic acid (320 mg, 1.12 mmol) in dry tetrahydrofuran (10 mL) was added borane-tetrahydrofuran (0.67 mL, 6.7 mmol) dropwise. The mixture was stirred at room temperature for 3 hours. The reaction mixture was quenched by water and extracted with dichloromethane. The organic layers were combined, dried over sodium sulfate, and concentrated to give the title compound (280 mg, 92%) as a colorless oil. 1H NMR (500 MHz, DMSO-d6) δ 7.05 (m, 2H), 6.86 (d, 1H), 4.57 (t, 1H), 3.73 (s, 3H), 3.55 (d, 2H), 2.05-2.17 (m, 4H), 1.95 (m, 1H), 1.69 (m, 1H).
