To a mixture of 2.4 g (0.02 mole) of benzotriazole and 1.98 mL (0.02 mole) of cyclopentylamine in 100 mL of ether was added dropwise 1.5 mL (0.02 mole) of 37% aqueous formaldehyde. The reaction mixture was stirred at room temperature for 6 hours. The solution was dried over calcium chloride, filtered and concentrated under reduced pressure. The solid was washed with hexane and dried to give benzotriazol-1-ylmethyl-cyclopentyl-amine as a white solid.
