Procedure

To a solution of 6-(5-Amino-2-methyl-phenyl)-2-[4-(4-methyl-piperazine-1-carbonyl)phenylamino]-7,8-dihydro-6H-pyrido[4,3-d]pyrimidin-5-one (70.7 mg, 0.15 mmol), 3-Trifluoromethyl benzoic acid (28.5 mg, 0.15 mmol), and DIPEA (78 μl, 0.45 mmol) in DMF was added HATU (59 mg, 0.15 mmol), and the reaction mixture was stirred for 3 hour at room temperature. The reaction mixture was diluted with ethylacetate and washed with 5% aqueous sodium bisulphate solution, saturated aqueous sodium bicarbonate solution and brine. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product obtained was purified by column chromatography (SiO2, 2-10% methanol in chloroform) to give 69.8 mg (72.3%) of N-(4-Methyl-3-{2-[4-(4-methyl-piperazine-1-carbonyl)phenylamino]-5-oxo-7,8-dihydro-5H-pyrido[4,3-d]pyrimidin-6-yl}-phenyl)-3-trifluoromethyl-benzamide [24] as a pale yellow solid.
