A solution of 7-(1,1-dimethylethyl)-2,3-benzofurandione (1.0 g, 5 mmol) and 4-[2-(3,4-dimethoxyphenyl)ethyl]benzenamine (1.0 g, 4 mmol) in 10 ml of dichloromethane is stirred at room temperature for 48 hours. The solvent is evaporated and the residue crystallized from ether/hexane. Recrystallization from acetonitrile gave the pure product, (1.0 g) mp 143°-144° C.
