실험 절차

To 6-aminoisoquinolin-1-ol in DMF was added methoxytrimethylsilane and (R)-tert-butyl 2-fluoro-2 oxo-1-(thiophen-3-yl)ethylcarbamate and the solution was stirred at room temperature for 6 h. The mixture was poured into EtOAc, washed with NH4Cl(sat)/HCl (1N) followed by NaHCO3 (0.05%), dried (Na2SO4), filtered and evaporated. Column chromatography (SiO2, 5% MeOH, CH2Cl2) gave pure (R)-tert-butyl 2-(1-hydroxyisoquinolin-6-ylamino)-2-oxo-1-(thiophen-3-yl)ethylcarbamate) (91.8% ee by Chiracel OD-RH).
