Rac-(1r,4r)-4-methoxycyclohexane-1-carboxylic acid → (4-Methoxycyclohexyl)methanol

4-Methoxycyclohexanecarboxylic acid (7 g) in tetrahydrofuran (20 mL) was treated with 1 M (in tetrahydrofuran) borane-tetrahydrofuran complex (100 mL) overnight. The mixture was concentrated and the residue was dissolved in methanol (100 mL) and concentrated HCl (10 mL). The resulting mixture was stirred for 1 hour and concentrated. The residue was dissolved in dichloromethane and washed with water. The organic layer was dried over Na2SO4, filtered, and concentrated to give the title compound.
