Procedure

250 g of tricyclo-[3.2.2.02.4 ]-non-8-ene-6,7-dicarboxylic acid anhydride (prepared from cycloheptatriene and maleic acid anhydride, K. Alder, Ber. 86, 1528-39 (1953)) and 200 g of 4-nitroaniline are refluxed in 1500 ml of glacial acetic acid for 3 hours. The reaction mixture cooled to 60° C is poured into 2000 ml of hot water, whereupon the crude product precipitates. After cooling, the crude product is filtered off, dried, and recrystallised from ethyl acetate; M.P. 210°-212° C.
