To a solution of 2-[4-(4-Methyl-piperazin-1-yl)-phenylamino]-5-oxo-8-phenyl-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carbonitrile (Example 13F, 9 mg) in 1 mL of t-butanol was added potassium hydroxide (ground, 5 mg). The mixture was stirred at 85° C. for 1 hour. After cooling to rt, water was added and the precipitates were extracted into EtOAc. The organic layer was washed with brine and dried over Na2SO4. The solvent was evaporated under vacuum to leave 2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-5-oxo-8-phenyl-5,8-dihydro-pyrido[2,3-d]pyrimidine-6-carboxylic acid amide as a yellow solid (7.2 mg, 79%). 1H NMR (300 MHz, CDCl3) δ (ppm): 10.64 (br, 1H), 10.30 (s, 1H), 9.17 (s, 1H), 7.71 (m, 3H), 7.53 (br, 1H), 7.43 (m, 2H), 6.94 (br, 2H), 6.35 (br, 2H), 5.06 (br, 1H), 3.12 (m, 4H), 2.59 (m, 4H), 2.37 (s, 3H). Mass Spectrum (LCMS, ESI pos.) Calcd. For C25H25N7O2: 456.51 (M+H), Found: 456.6.
