Participants

Reaction Steps

Using an analogous procedures to those described in Example 15, 2-[4-(6-cyano-7-methoxyquinolin-4-yloxy)phenyl]acetic acid was reacted with 3-(N-tert-butoxycarbonyl-N-cyclopropylaminomethyl)-5-methylaniline and the product was reacted with trifluoroacetic acid. The resultant product was purified by column chromatography on silica using a solvent gradient from 100:0 to 9:1 mixtures of ethyl acetate and methanol as eluent. There was thus obtained the title compound in 48% yield. A portion of the material so obtained was dissolved in methylene chloride and a solution of maleic acid (1 equivalent) in ethanol was added. The resultant solution was evaporated to provide a maleate salt of the title compound which gave the following characterising data:—1H NMR: (DMSOd6) 0.73 (m, 4H), 2.3 (s, 3H), 2.64 (m, 1H), 3.72 (s, 2H), 4.07 (s, 3H), 4.11 (s, 2H), 6.01 (s, 2H), 6.52 (m, 1H), 7.0 (s, 1H), 7.3 (d, 2H), 7.35 (s, 1H), 7.5 (d, 2H), 7.62 (s, 1H), 7.66 (s, 1H), 8.76 (m, 2H), 10.26 (s, 1H); Mass Spectrum: M+H+ 493.
