Reaction Steps

As in Example 37, 9-chloro-2-(2-furyl)-5-methylthio[1,2,4]triazolo[1,5-c]quinazoline (1.06 g) is reacted in a stainless steel pressure vessel with isopropylamine (50 ml) at 150° (external temperature) for 6 hours to afford 9-chloro-2-(2-furyl)-5-isopropylimino-5,6-dihydro-[1,2,4]triazolo[1,5-c]quinazoline, which is purified by ethanol recrystallization, mp. 140°-141°.
