反応手順

A solution containing 3-cyclopentyloxy-4-methoxybenzyl alcohol (112 grams, 0.50 mol), prepared as described in step a), in 1 liter of methylene chloride was stirred at room temperature with concentrated HCl (110 milliliters, 1.2 mol) for 3 hours, at which time the reaction was done by TLC. The layers were separated and the methylene chloride solution was washed twice with water and evaporated under reduced pressure to give 3-cyclopentyloxy-4-methoxybenzyl chloride (119 grams, 100%).
