A mixture of 2-(but-3-en-1-yl)benzaldehyde (500 mg, 3.12 mmol) in MeOH (10 mL) was added NaBH4 (118 mg, 3.12 mmol) and the mixture was stirred at rt for 1 h. It was then added water, extracted with EtOAc. The organic layer was dried over MgSO4, filtered and concentrated to obtain an oil, which was then purified by biotage, eluting with 10% EtOAc/hexane to obtain (2-(but-3-en-1-yl)phenyl)methanol (320 mg, 1.973 mmol, 63.2% yield) as an oil. 1H NMR (400 MHz, CDCl3) δ 7.44-7.37 (m, 1H), 7.33-7.21 (m, 3H), 5.91 (ddt, J=16.9, 10.2, 6.6 Hz, 1H), 5.13-4.99 (m, 2H), 4.76 (d, J=5.9 Hz, 2H), 2.86-2.77 (m, 2H), 2.44-2.35 (m, 2H).
