Procedure
To a stirred solution of 3-amino-1,2,4-triazole (1.5 g, 0.018 mol), 7.5 ml of 1N HCl, and 50 ml of methanol was added 3-cyclopentyloxy-4-methoxybenzaldehyde (3.3 g, 0.015 mol) and sodium cyanoborohydride (0.945 g, 0.015 mol). A precipitate formed slowly and after 20 hours the precipitate was filtered and recrystallized from methanol (135 ml) to give 1.0 g (0.0034 mol. 23%) of the title compound, mp 203-204° C.
