Procedure

Sodium acetate (0.65 g), 2,4-dichloroquinazoline (0.52 g) and 4'-aminomethyl[1,1'-biphenyl]-2-carboxylic acid methyl ester (0.73 g) were suspended in 25 mL of tetrahydrofuran. The reaction was stirred at room temperature for approximately 18 hours at which time the solvents were evaporated. The residue was loaded onto a silica gel column and the desired product was eluted with ethyl acetate/hexane (1:1). The yield was 0.75 g (71%) (m.p.=75°-90° C.): 1H NMR (DMSO-d6, 300 MHz) δ9.30 (t, J=6 Hz, 1H), 8.33 (d, J=8.1 Hz, 1H), 7.81 (m, 1H), 7.71 (m, 1H), 7.60 (m, 3H), 7.45 (m, 4H), 7.25 (d, J=8.1 Hz, 2H), 4.80 (d, J=5.8 Hz, 2H), 3.58 (s, 3H); positive FAB MS m/e 404(MH). Anal. calcd for C23H18ClN3O2 : C, 68.40; H, 4.49; N, 10.40. Found: C,68.09; H, 4.57; N, 10.10.
