Triethylamine → N-[2-methyl-5-(3-morpholinobenzamido)phenyl]thiophene-2-carboxamide

Thiophene-2-carbonyl chloride (0.069 g) was added to a stirred suspension of N-(3-amino-4-methylphenyl)-3-morpholinobenzamide (0.104 g), triethylamine (0.15 ml) and methylene chloride (20 ml) and the resultant mixture was stirred at ambient temperature for 4 hours. The organic phase was washed with water and with a saturated aqueous sodium bicarbonate solution, dried (MgSO4) and evaporated. The residue was dissolved in methylene chloride (2 ml) and diethyl ether (20 ml) was added to give a precipitate which was isolated by filtration, washed with diethyl ether and dried. There was thus obtained the title compound (0.047 g); NMR Spectrum: (DMSOd6) 2.18 (t, 3H), 3.18 (t, 4H), 3.76 (t, 4H), 7.14 (d, 1H), 7.20 (m, 2H), 7.38 (m, 2H), 7.41 (s, 1H), 7.58 (m, 1H), 7.78 (s, 1H), 7.82 (d, 1H), 7.98 (d, 1H), 9.93 (s, 1H), 10.13 (s, 1H); Mass Spectrum: M+H+ 422.
