Procedure

A stirred solution of 0.83 g. of the N-(1-methyldecyl)-3-(3-aminophenyl)-2-butenamide from Preparation 28 in 25 ml. of toluene was heated on a steam bath, and 0.31 g. of glutaric anhydride was added in one portion. After 5 minutes, the solution was concentrated in vacuo, which caused a gum to form. The remaining toluene was poured off, and the residue was induced to solidify by trituration under petroleum ether. The solid was recrystallized three times from acetonitrile, giving 261 mg. of the title compound, m.p. 115°-117.5° C. The IR spectrum (KBr disc) showed absorptions at 3279, 2941, 1709, 1667, 1639, 1600 and 1550 cm-1. The NMR spectrum (DMSO-d6) showed absorptions at 0.82 (m, 3H), 0.94 (m, 3H), 1.21 (s, 16H), 1.85 (m, 2H), 2.05 (m, 3H), 2.32 (m, 4H, under DMSO-d6), 3.60 (m, 1H), 5.89 (d, 1H), 7.20 (m, 6H) and 9.80 (s, 1H) ppm.
