실험 절차

A sealed tube equipped with a magnetic stirrer was charged with 114a (228 mg, 0.56 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 (215 mg, 0.56 mmol), Pd (dppf)Cl2 (47 mg, 0.056 mmol), 1.0 M NaOAc (93 mg, 1.12 mmol, 2.0 equiv), 1.0 M K3PO4 (240 mg, 1.12 mmol, 2.0 equiv), and acetonitrile (3 mL). After three cycles of vacuum/argon flush, the mixture was heated at 110° C. for 2 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica gel column chromatography eluting with dichloromethane/methanol (10:1, V/V) to 114b (360 mg, 96%) as a brown solid. LCMS: [M+H] 665.
