Participants

Reaction Steps

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.12 g) in methylene chloride (5 ml) was added to a stirred mixture of 3,4-dimethoxybenzoic acid (0.91 g), N-(3-amino-4-fluorophenyl)-3-dimethylaminobenzamide (0.14 g), DMF (2 ml) and 4-dimethylaminopyridine (0.004 g). The reaction mixture was stirred at ambient temperature for 18 hours. Water (20 ml) and methylene chloride (10 ml) were added. The organic phase was washed with a saturated aqueous sodium bicarbonate solution, dried (MgSO4) and evaporated. The residual oil was purified by column chromatography on silica gel using a 49:1 mixture of methylene chloride and methanol as eluent. The material so obtained was triturated under diethyl ether. There was thus obtained the title compound (0.084 g) as a colourles solid, m.p. 187-188° C.; NMR Spectrum: (CDCl3) 3.02 (s, 6H), 3.97 (s, 6H), 6.86 (m, 1H), 6.93 (d, 1H), 7.09 (d, 1H), 7.16 (t, 1H), 7.25 (m, 1H), 7.32 (t, 1H), 7.41 (m, 1 H), 7.5 (d, 1H), 7.88 (m, 1H), 7.97 (s, 1H), 8.04 (s, 1H), 8.42 (m, 1H);
