A mixture of 3-[5-(2-chloropyrid-4-ylcarbonylamino)-2-methylphenyl]-6-(4-methylpiperazin-1-yl)-3,4-dihydroquinazolin-4-one (0.18 g) and pyrrolidine (2 ml) was stirred and heated to 100° C. for 16 hours. The mixture was cooled to ambient temperature and poured into water. The resultant solid was isolated, washed with water and dried under vacuum at 40° C. There was thus obtained the title compound (0.11 g); NMR Spectrum: (DMSOd6) 1.94-1.97 (m, 4H), 2.04 (s, 3H), 2.22 (s, 3H), 2.45-2.49 (m, 4H), 3.25-3.28 (m, 4H), 3.4-3.45 (m, 4H), 6.85 (s, 1H), 6.96 (d, 1H), 7.42 (d, 1H), 7.42 (d, 1H), 7.44 (s, 1H), 7.62 (s, 2H), 7.77-7.79 (m, 2H), 8.07 (s, 1H), 8.2 (s, 1H), 10.42 (s, 1H); Mass Spectrum: M+H+ 524.
