Reaction Steps

As in Example 37, 2-(2-furyl)-5-methylthio-[1,2,4]triazolo[1,5-c]quinazoline is reacted with ammonium hydroxide (200 ml) saturated with ammonia at 0° in the stainless steel pressure vessel at 150° and 220 p.s.i. over six hours to afford 2-(2-furyl)-5-imino-5,6-dihydro[1,2,4]triazolo[1,5-c]quinazoline, mp 282°-285° after methanol recrystallization.
