実験手順

To a mixture of 1-(methylsulfonyl)piperidin-4-ol (618 mg, 3.45 mmol, 1.6 eq) in THF (5 mL) at 0° C., NaH (60% in mineral oil, 173 mg, 4.32 mmol, 2.0 eq) was added and the resulting mixture was stirred for 10 min. To this mixture, (S)-(9H-fluoren-9-yl)methyl 1-(1,8-dichloroisoquinolin-3-yl)ethylcarbamate 69 (1.0 g, 2.16 mmol, 1.0 eq) was added and the resulting mixture was stirred at reflux for 2 h. The mixture was cooled to RT and poured into water (20 mL). The mixture was extracted with ethyl acetate (3×20 mL). The combined organic layer was washed with brine, dried over Na2SO4 and filtered. The filtrate was concentrated in vacuo and the residue was purified by flash column chromatography on silica gel (3% MeOH-DCM) to afford the product (S)-1-(8-chloro-1-(1-(methylsulfonyl)piperidin-4-yloxy)isoquinolin-3-yl)ethanamine (175).
