Reaction Steps

A solution of 2-(3-cyclopentyloxy-4-methoxybenzyl)-5-chloro-7-allylbenzoxazole (1.2 g, 3.0 mmol) in ethyl acetate (50 ml) was hydrogenated over 0.104 g of 10% Pd on carbon catalyst in a Parr apparatus at 23 psi until hydrogen uptake ceased. The catalyst was filtered and the solvent was evaporated. The residue was recrystallized from hexane to give the title compound (0.55 g, 46%), mp 54-55° C.
