실험 절차

Diisopropylethylamine (0.4 ml) was added to a stirred mixture of N-(5-amino-2-ethylphenyl)-3-(4-methylpiperazin-1-ylmethyl)benzamide (0.2 g), dibenzofuran-4-carboxylic acid (0.133 g), 2-(7-azabenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate(V) (0.22 g) and methylene chloride (10 ml) and the mixture was stirred at ambient temperature for 16 hours. The mixture was evaporated and the residue was partitioned between methylene chloride and a saturated aqueous sodium bicarbonate solution. The organic phase was dried over magnesium sulphate and evaporated. The residue was purified by column chromatography on silica using increasingly polar mixtures of methylene chloride and methanol as eluent. The material so obtained was dissolved in acetone and reprecipitated by the addition of isohexane. There was thus obtained the title compound (0.164 g); NMR Spectrum: (DMSOd6) 1.15 (t, 3H), 2.25 (s, 3H), 2.35-2.5 (m, 8H), 2.6 (m, 2H), 3.55 (s, 2H), 7.3 (d, 1H), 7.4-7.6 (m, 5H), 7.65 (m, 1H), 7.8-7.9 (m, 5H), 8.2 (d, 1H), 8.35 (d, 1H), 9.95 (s, 1H), 10.43 (s, 1H); Mass Spectrum: M+H+ 547.
