Participants

Reaction Steps

Using an analogous procedure to that described paragraph (A) in the portion of Example 4, 4-methyl-3-[6-(4-(2-methoxyethyl)piperazin-1-yl)-4-oxoquinazolin-3(4H)-yl]benzoic acid was reacted with 3-aminoisoxazole to give 3-[6-(4-(2-methoxyethyl)piperazin-1-yl)-4-oxoquinazolin-3(4H)-yl]-N-isoxazol-3-yl-4-methylbenzamide; NMR Spectrum: (DMSOd6) 2.18 (s, 3H), 2.58 (m, 6H), 3.26 (m, 7H), 3.47 (t, 2H), 7.05 (s, 1H), 7.50 (s, 1H), 7.66 (m, 3H), 8.10 (m, 2H), 8.13 (s, 1H), 8.87 (s, 1H), 11.48 (s, 1H); Mass Spectrum: M+H+ 489.
