Procedure

1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (0.165 g) was added to a stirred mixture of 3-(tetrahydrofuran-3-yloxy)benzoic acid (0.15 g), 1-hydroxybenzotriazole (0.146 g) and DMF (5 ml) which had been cooled to 0° C. The reaction mixture was stirred at 0° C. for 5 minutes and a solution of N-(3-amino-4-methylphenyl)-3-morpholinobenzamide (0.224 g) in DMF (1 ml) was added. The reaction mixture was allowed to come to ambient temperature and was stirred for 16 hours. The reaction mixture was poured into water and the resultant solid was isolated and purified by column chromatography on silica using a 99:1 mixture of methylene chloride and methanol as eluent. There was thus obtained the title compound (0.228 g); NMR Spectrum: (DMSOd6) 1.99 (m, 1H), 2.18 (s, 3H), 2.25 (m, 1H), 3.17 (t, 4H), 3.72 (t, 4H), 3.88 (m, 4H), 5.13 (m, 1H), 7.11 (m, 2H), 7.21 (d, 1H), 7.39 (m, 5H), 7.56 (m, 2H), 7.79 (m, 2H), 9.83 (s, 1H), 10.11 (s, 1H); Mass Spectrum: M+H+ 502.
