실험 절차

To a solution of [3-ethoxy-4-(5-fluoro-1,2,3,4-tetrahydro-isoquinolin-8-yl)-phenyl]-acetic acid ethyl ester (1.49 g, 4.2 mmol, 1.00 eq.) and N-ethyldiisopropylamine (3.56 mL, 20.8 mmol, 5.00 eq.) in DCM (50 mL), carbonic acid 2,5-dioxo-pyrrolidin-1-yl ester 4-fluoro-benzyl ester (1.17 g, 4.4 mmol, 1.05 eq.) was added. The mixture was stirred at r.t. for 18 hours. The solution was diluted with sat. aq. NaHCO3 soln. (100 mL). The layers were separated. The aq. phase was extracted with DCM (2×). The comb. org. phases were dried over MgSO4, filtered, and concentrated in vacuo. The residue was purified by flashmaster (column: 100 g, flow: 45 mL/min, 100 fractions of 45 mL, Heptane 100% to Heptane+40% AcOEt) to yield the title compound as a colorless oil.
