Reaction Steps

A mixture of 90 g (0.448 mol) of 3,4-bromomethylenedioxybenzene, 50 g (0.37 mol) of acetanilide, 12 g (0.075 mol) of copper sulfate, and 80 g (0.579 mol) of potassium carbonate was reacted in the same manner as in Example 5 (2) to obtain a crude reaction product. A mixture of this crude product, 121.4 g (1.84 mol) of 85% KOH, and 200 ml of methanol was refluxed overnight and then concentrated. Water was added thereto. The resultant mixture was extracted with toluene twice. The toluene phase was washed with water three times, dried, and then concentrated. The residue was distilled under vacuum to obtain 65.91 g of N-3,4-methylenedioxyphenyl-N-phenylamine.
