Tetrahydrofuran → [6-(5-Amino-2-methyl-phenyl)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-2-yl]-(4-chloro-phenyl)amine

Participants

Reaction Steps

To a solution of (4-Chloro-phenyl)-[6-(2-methyl-5-nitro-phenyl)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-2-yl]amine (100 mg, 0.25 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)-5,6,7,8-tetrahydro-pyrido[4,3-d]pyrimidin-2-yl]-(4-chloro-phenyl)amine [12]as a off white solid [Yield: 81.5 mg, 88.2%]
