Reaction Steps
To a microwave tube equipped with a stirring bar, 301a (500 mg, 1.077 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 (546 mg, 1.292 mmol), Pd(PPh3)4 (62 mg, 0.054 mmol), Na2CO3 aqueous solution (1.0 N, 3.55 mL, 3.55 mmol), 1,2-dimethoxyethane (4.3 mL) were added. The mixture was reacted in microwave at 130° C. for 10 min. Methylene chloride (200 mL) was added and the resulting mixture was washed with water (3×30 mL), brine (30 mL), dried over MgSO4, filtered, and removed solvent in vacuo. Silica gel column chromatography (methanol:methylene chloride=5:95) gave 301b.
