4-n-Propylaniline (0.11 g) was added to a stirred suspension of 5-(4-cyanobenzamido)-2-methylbenzoyl chloride (0.224 g), triethylamine (0.21 ml) and methylene chloride (5 ml) and the resultant mixture was stirred at ambient temperature for 16 hours. The mixture was filtered and the filtrate was evaporated. The residue was purified by column chromatography on silica using increasingly polar mixtures of methylene chloride and methanol as eluent, There was thus obtained the title compound (0.049 g); NMR Spectrum: (DMSOd6) 0.87 (t, 3H), 1.56 (m, 2H), 2.33 (s, 3H), 2.48 (m, 2H), 7.13 (d, 2H), 7.28 (d, 1H), 7.63 (m, 2H), 7.83 (m, 3H), 8.01 (d, 1H), 8.1 (m, 2H); Mass Spectrum: M+H+ 398.
