Reaction Steps

To a solution of 2-[3-Methyl-4-(4-methyl-piperazin-1-yl)-phenylamino]-6-(2-methyl-5-nitro-phenyl)-7,8-dihydro-6H-pyrido[4,3-d]pyrimidin-5-one (100 mg, 0.198 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-[3-methyl-4-(4-methyl-piperazin-1-yl)-phenylamino]-7,8-dihydro-6H-pyrido[4,3-d]pyrimidin-5-one [19] (Yield: 81.72 mg, 86.9%) as a off white solid.
