Procedure

Sodium acetate (2.34 g), 4'-aminomethyl(1,1'-biphenyl)-2-carboxylic acid, methyl ester (1.99 g) and 1.66 g of 4-chloro-2-trifluoromethylquinazoline were added to 50 mL of tetrahydrofuran. The resulting suspension was stirred at 40°-50° C. for 72 hours. All the THF was removed by evaporation and the residue was partitioned between ethyl acetate and brine. The organic layer was dried over anhydrous magnesium sulfate, filtered and evaporated. The residue was purified on silica gel chromatography to yield. 3.46 g (40%) of the desired product (M.P.=135°-142° C.): 1H NMR (DMSO-d6, 400 MHz) δ 9.43 (t, J=6 Hz, 1H), 8.41 (d, 7.9 Hz, 1H), 7.88 (m, 2H), 7.70 (m, 2H), 7.58 (m, 1H), 7.43 (m, 4H), 7.25 (m, 2H), 4.85 (d, J=5.9 Hz, 2 H), 3.56 (s, 3H); positive FAB MS m/e 438 (MH). Anal Calcd for C24H18F3N3O2.0.5H2O: C, 64.57; H, 4.29; N, 9.41. Found: C, 64.83; H, 4.02; N, 9.48.
