A solution of 3-cyclopentyloxy-4-methoxybenzyl alcohol (112 g, 0.50 mol) prepared as described above, in 1 liter of methylene chloride was stirred at room temperature with concentrated HCl (110 ml, 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 g, 100%).
