Reaction Steps
A mixture consisting of 0.15 mol (32.1 g) of 4,5-dinitro-2-methoxyphenol, prepared in Example 2, 150 ml of formamide and 200 ml of 28% strength ammonia solution in water is heated to 95° C. for 8 hours in an autoclave. After the mixture is cooled, the expected product crystallizes. It is dissolved in the minimum quantity of dimethylformamide, and is then precipitated by adding water. It melts at 208° C.
