実験手順

A sealed tube was charged with the mixture of 172a (167 mg, 0.48 mmol), 2-(2-(hydroxymethyl)-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-1(2H)-one 114a (231 mg, 0.48 mmol), Pd(dppf)Cl2 (39 mg, 0.048 mmol), and Na2CO3 (101 mg, 0.96 mmol) in N,N-dimethylformamide (18 mL). The system was evacuated and then refilled with N2. And the reaction mixture was heated at 150° C. under microwave irradiation for 1 h. Then, the mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by column chromatography eluting with 15:1 methylene chloride/methanol to give 172b as a brown solid (140 mg, 50%). MS: [M+H]+ 606.
