실험 절차

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 172a (200 mg, 0.71 mmol), 3-(acetoxymethyl)-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)pyridin-4-ylboronic acid 113i (272 mg, 0.71 mmol), Pd(dppf)Cl2 (58 mg, 0.071 mmol), sodium acetate (193 mg, 1.42 mmol), K3PO4 (321 mg, 1.42 mmol), water (0.5 mL) and acetonitrile (10 mL). After three cycles of vacuum/argon flush, the mixture was stirred at 100° C. for 3 h. After this time the reaction was filtered and the filtrate was evaporated in vacuo. The resulting residue was recrystallized from ethyl acetate to afford 172b as yellow solid (380 mg, 99%). MS-ESI: [M+H]+ 541.2
