Procedure

A solution of 0.1 mol (19.6 g) of 2-methylamino-4,5-methylenedioxy-1-nitrobenzene, prepared according to Example 3, in 80 ml of a 30% strength solution of sodium methylate in methanol is brought for 15 minutes to the refluxing temperature of the methanol. The reaction medium is diluted with 500 ml of water. After the filtrate has been neutralized with acetic acid, the expected product precipitates.
