実験手順

A solution of 3-cyclopentyloxy-4-methoxybenzaldehyde (38 grams, 0.17 mol) in 40 milliliters of ethanol and sodium borohydride (1.63 grams,0.043 mol) was stirred for 2 hours at room temperature until complete by TLC. The reaction was diluted with water and extracted with ethyl acetate. Evaporation of the ethyl acetate afforded 3-cyclopentyloxy-4-methoxybenzyl alcohol (37 grams, 98%) suitable for the next step.
