Reaction Steps

Forty-one g of 3,4,-methylenedioxyphenethylamine (0.25 moles) was refluxed with 36 g of phthalic anhydride (0.28 moles) and 65 ml. of acetic acid for 2.5 hours. The mixture was cooled whereupon it solidified. The solid mass was broken up and triturated with water and the solid recovered by filtration. Recrystallization from 300 ml of acetic acid and 125 ml of water gave white crystals of the above-named product, m.p. 139°-140.5°.
