Reaction Steps

A mixture of 9-chloro-2-(2-furyl)-5-mercapto[1,2,4]triazolo[1,5-c]quinazoline (5.6 g) and aniline (40 ml) is stirred at 150° for 66 hours under nitrogen. The mixture is heated on a rotary evaporator under water pump vacuum to remove residual aniline and recrystallized from aqueous ethanol to afford pure 9-chloro-2-(2-furyl)-5-phenylimino-5,6-dihydro-[1,2,4]triazolo[1,5-c]quinazoline, mp 231°-233°.
