Participants

Reaction Steps

Oxalyl chloride (0.142 ml) was added to a mixture of N-(1-ethylpyrazol-4-yl)-2-[4-(6-carboxyquinolin-4-yloxy)-2-methoxyphenyl]acetamide (0.15 g) and methylene chloride (6 ml) and the resultant mixture was stirred at ambient temperature for 10 minutes. Diethyl ether (10 ml) was added and the resultant precipitate was recovered and dried under vacuum. The material so obtained was suspended in methylene chloride and methylamine gas was passed into the suspension until a clear solution was obtained. The solvent was evaporated and the residue was purified by column chromatography on silica using a gradient of 100:0 to 19:1 of methylene chloride and methanol as eluent. There was thus obtained the title compound (0.102 g); 1H NMR: (DMSOd6) 1.33 (t, 3H), 2.85 (d, 3H), 3.61 (s, 2H), 3.78 (s, 3H), 4.07 (q, 2H), 6.7 (d, 1H), 6.87 (m, 1H), 7.01 (d, 1H), 7.37 (d, 1H), 7.42 (s, 1H), 7.88 (s, 1H), 8.08 (d, 1H), 8.24 (m, 1H), 8.77 (d, 1H), 8.82 (q, 1H), 8.87 (d, 1H), 10.06 (s, 1H); Mass Spectrum: M+H+ 460.
