Reaction Steps

One operates as in Example 12, but the 1-cyano-1-ethoxycarbonyl-4-morpholino-4-phenyl-2-aza-1,3-butadiene is replaced by 1-cyano-1-methoxycarbonyl-3-methyl-4-morpholino-4-phenyl-2-aza-1,3-butadiene and the reaction is effected at -30°C. 4.1 parts of 1-cyano-1-methoxycarbonyl-3-methyl-4-amino--4-phenyl-2-aza-1,3-butadiene are obtained after a reaction time of 3 days. After recrystallisation from methanol the product melts at 145°C.
