To a solution of 4-methoxy-3-(3,5,5,8,7-pentamethyl-5,6,7,8-tetrahydronaphthalen-2-yl) benzaldehyde (200 mg, 0.59 mmol) in methanol (5 mL) was added at 0° C. in small portions sodium borohydride (70 mg, 1.77 mmol). The solution was stirred 1 hour at 0° C. then quenched with 2N HCl. The reaction mixture was diluted with ethyl acetate and washed successively with water and brine, dried over anhydrous magnesium sulfate, filtered and evaporated to afford 195 mg (98%) of 4-methoxy-3-(3,5,5,8,7-pentamethyl-5,6,7,8-tetrahydronaphthalen-2-yl) benzyl alcohol.
