Using an analogous procedure to that described paragraph (A) in the portion of Example 4, 3-[8-cyano-6-(4-ethylpiperazin-1-yl)-4-oxoquinazolin-3(4H)-yl]-4-methylbenzoic acid was reacted with 3-aminoisoxazole to give 3-[8-cyano-6-(4-ethylpiperazin-1-yl)-4-oxoquinazolin-3(4H)-yl]-N-isoxazol-3-yl-4-methylbenzamide; NMR Spectrum: (DMSOd6) 1.03 (t, 3H), 2.19 (s, 3H), 2.38 (q, 2H), 2.53 (m, 4H), 3.35 (m, 4H), 7.04 (s, 1H), 7.60 (d, 1H), 7.69 (s, 1H), 8.10 (m, 3H), 8.29 (s, 1H), 8.84 (s, 1H), 11.47 (s, 1H); Mass Spectrum: M+H+ 484.
