Procedure
A mixture of homophthalic acid (9.0 g., 0.05 mole) and allylamine (2.8 g., 0.05 mole) was heated by an oil bath to 185°-190° C. for 40 minutes. The mixture solidified upon cooling, and was recrystallized twice from isopropanol, giving 2-allylisoquinoline-1,3 (2H, 4H)-dione, 4.6 g. (46% yield), m.p. 75°-77° C.
