실험 절차

To a reaction vessel containing 7-benzyl-4-chloro-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidine (518 mg, 2 mmol), 3-(isoquinolin-3-yl)-4-methylaniline (470 mg, 2 mmol), pTSA (144 mg, 0.6 mmol) is added isopropanol (7 ml). The vessel is purged with nitrogen, sealed. The reaction vessel is placed in a microwave reactor and irradiated for 30 minutes at 130° C. The reaction mixture is cooled to room temperature and diluted with ethyl acetate. It is washed with saturated aqueous NaHCO3, water and brine, dried over anhydrous MgSO4 and concentrated. The residue is subjected to silica gel flash chromatography (2% methanol in dichloromethane) to afford 7-Benzyl-N-(3-(isoquinolin-3-yl)-4-methylphenyl)-5,6,7,8-tetrahydropyrido[3,4-d]pyrimidin-4-amine as a brown solid. LC-MS m/z: 458.2 (M+1).
