3-(3-Chlorophenyl)prop-2-enoic acid → 3-(3-Chlorophenyl)propan-1-ol

Participants

Reaction Steps

A slurry of lithium aluminum hydride (2.08 g, 54.7 mmol) in THF (100 mL) was cooled to −78 C. A solution of 3-chlorocinnamic acid (5.00 g, 27.4 mmol) in THF (25 mL) was added dropwise. The cold bath was removed and the mixture was warmed to room temperature. After 6 h, the reaction was quenched by addition of sodium sulfate decahydrate and the mixture was stirred overnight. The solids were removed by filtration with the aid of EtOAc and the organic solution was washed with brine, dried over MgSO4, filtered, and concentrated in vacuo to yield 3-(3-chloro-phenyl)-propan-1-ol (5.17 g) as an oil. 1H NMR (400 MHz, CDCl3) δ 7.30-7.07 (m, 4H), 5.06 (bs, 1H), 3.67 (m, 2H), 2.69 (m, 2H), 1.89 (m, 2H).
