Versuchsvorschrift

A microwave tube equipped with a magnetic stirrer was charged with 126a (210 mg, 0.65 mmol), 2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl acetate 114a (330 mg, 0.7 mmol), DME (6 mL) and 1M aqueous sodium carbonate (1.9 mL). After bubbling N2 for 15 min, Pd(PPh3)4 (38 mg, 0.03 mmol) was added. The mixture was heated in microwave to 135° C. for 15 min. After this time, ethyl acetate (10 mL) and water (10 mL) were added. The separated aqueous layer was extracted with ethyl acetate (2×10 mL). The combined organics were washed with brine (20 mL), dried over sodium sulfate, filtered and concentrated under reduced pressure. The resulting residue was purified by column chromatography eluting with a gradient of CH2Cl2-9:1 CH2Cl2:MeOH to afford a 36% yield (140 mg) of 126b.
