4-Isobutylbenzoic acid → [4-(2-Methylpropyl)phenyl]methanol

Participants

Reaction Steps

A solution of lithium aluminum hydride (30 mL, 1M in THF, 30 mmol) was added dropwise to a solution of 4-isobutylbenzoic acid (5.34 g, 30 mmol) in THF (50 mL) at 0° C. The ice bath was removed and the reaction was stirred at room temperature for 1 h. The reaction was carefully poured onto a mixture of ice and aqueous HCl (10 mL, 6N). The product was extracted into EtOAc and the organic solution was dried (MgSO4), filtered, and concentrated to obtain (4-isobutyl-phenyl)-methanol which was used in the next step without further purification. 1H NMR (400 MHz, CDCl3) δ 7.26 (d, 2H), 7.13 (d, 2H), 4.65 (s, 2H), 2.46 (d, 2H), 1.85 (m, 1H), 0.89 (d, 6H).
