Procedure

To a microwave tube equipped with a stirring bar, 130c (250 mg, 0.663 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 (338 mg, 0.729 mmol), Pd(PPh3)4 (38.3 mg, 0.033 mmol), Na2CO3 aqueous solution (1.0 N, 2.19 mL, 2.19 mmol), DME (2 mL) were added. The mixture was reacted in microwave at 135° C. for 15 min. CH2Cl2 (200 mL) was added and the resulting mixture was washed with water (30 mL×3), brine (30 mL×1), dried over MgSO4, filtered, and removed solvent in vacuo. Silica gel column chromatography (MeOH:DCM=5:95) gave 130d.
