2-(4-Methylpiperidin-1-yl)ethan-1-amine → 6-[2-(4-Methyl-1-piperidinyl)ethylamino]-7,8,9,10-tetrahydro-1,2,4-triazolo[3,4-a]phthalazine

A solution of 5.0 g of 6-chloro-7,8,9,10-tetrahydro-1,2,4-triazolo[3,4-a]phthalazine in 25 ml of 1-(2-aminoethyl)-4-methylpiperidine was heated at reflux for 15 hours and then poured into ice water. The resulting off-white solid was separated by filtration and recrystallized from toluene to give 6-[2-(4-methyl-1-piperidinyl)ethylamino]-7,8,9,10-tetrahydro-1,2,4-triazolo[3,4-a]phthalazine melting at about 180°-181° C.
