Participants

Reaction Steps

Using an analogous procedure to that described in Example 45, two equivalents of 1N methanesulfonic acid in ethyl acetate was reacted with N-cyclopropyl-4-methyl-3-[6-(4 methylpiperazin-1-yl)-4-oxoquinazolin-3(4H)-yl]benzamide to gave the title compound; NMR Spectrum: (DMSOd6) 0.56 (m, 2H), 0.70 (m, 2H), 2.13 (s, 1H), 2.40 (s, 6H), 2.87 (m, 1H), 2.89 (d, 3H), 3.10-3.30 (m, 4H), 3.58 (m, 2H), 4.05 (m, 2H), 7.52 (d, 1H), 7.59 (d, 1H), 7.71 (m, 2H), 7.84 (s, 1H), 7.91 (m, 1H), 8.22 (s, 1H), 8.47 (d, 1H), 9.74 (s, 1H).
