실험 절차

(S)-(9H-fluoren-9-yl)methy 1-(8-chloro-1-(tetrahydro-2H-pyran-4-ylcarbamoyl)isoquinolin-3-yl)ethylcarbamate (351) (20.0 g, 36.0 mmol, 1.0 eq) was suspended in morpholine (200 mL), and then stirred at 40-50° C. for 1 h. The reaction mixture was concentrated in vacuo and then 1,4-dioxane (200 mL) was added to the residue. The mixture was concentrated in vacuo. The operation was repeated for 3-4 times. The residue was purified by flash column chromatography on silica gel (2-10% MeOH-DCM) to afford (S)-3-(1-aminoethyl)-8-chloro-N-(tetrahydro-2H-pyran-4-yl)isoquinoline-1-carboxamide (352).
