実験手順

2.60 g of 3-(2-chloro-2-ethoxycarbonyleth-1-yl)-4-chloroaniline and 1.65 g of 4-methyl-3,4,5,6-tetrahydrophthalic anhydride were refluxed for 6 hours. After the mixture had been cooled and evaporated down, the residue was taken up in ethyl acetate and the solution was washed three times with water. The organic phase was dried over Na2SO4 and then evaporated down. Yield 3.0 g (75%); 1H-NMR (in d6 -DMSO/TMS): δ [ppm]=0.96 (d; 3H), 1.05 (t; 3H), 1.64-2.08 (m; 3H), 2.15-2.70 (m; 4H), 3.20-3.55 (m; 2H), 4.14 (q; 2H), 4.78 (dd; 1H), 7.26 (d; 1H), 7.34 (s; 1H), 7.55 (d; 1H).
