Reaction Steps
To a solution of 6-(2-Methyl-5-nitro-phenyl)-2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-7,8-dihydro-6H-pyrido[4,3-d]pyrimidin-5-one (100 mg, 0.211 mmol) in the mixed solvent of THF (5 ml) and methanol (5 ml) was added 10% Pd/C, and the reaction mixture was stirred for 12 hours at room temperature under a hydrogen balloon. The reaction mixture was filtered and the filtrate was concentrated under vacuum to give 6-(5-Amino-2-methyl-phenyl)-2-[4-(4-methyl-piperazin-1-yl)-phenylamino]-7,8-dihydro-6H-pyrido[4,3-d]pyrimidin-5-one [45] (Yield: 86.45 mg, 92.3%) as a white solid.
