실험 절차

To a solution of 6-benzyl-N-(3-(isoquinolin-3-yl)-4-methylphenyl)-5,6,7,8-tetrahydro-2,6-naphthyridin-1-amine (320 mg, 0.7 mmol) in dichloroethane is added DIEA (225 mg, 1.75 mmol) and 1-chloroethyl carbonochloridate (200 mg, 1.4 mmol). The reaction mixture is stirred at 90° C. for 12 hours. After cooling, the solvent is removed by rotary evaporation. The residue is redissolved in 20 ml of methanol and stirred at room temperature for 15 hours. After removing solvent, the crude product is purified by silica gel flash chromatography, eluted with 5% methanol in ethyl acetate to afford N-(3-(isoquinolin-3-yl)-4-methylphenyl)-5,6,7,8-tetrahydro-2,6-naphthyridin-1-amine as a light yellow solid. MS m/z 367.2 (M+1).
