Reaction Steps

Following Example 121b, 263a (158 mg, 0.5 mmol), 4-fluoro-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 210d (242 mg, 0.5 mmol), 1M sodium carbonate solution (2 mL, 2 mmol), tetrakis(triphenylphosphine)palladium(0) (29 mg, 0.025 mmol) and 1,2-dimethoxyethane (5 mL) were heated at 130° C. for 15 minutes in the microwave reactor. Work-up and flash column chromatography (silica, 60:35:5 methylene chloride/diethyl ether/methanol) gave a 98% yield (290 mg) of 263b as yellow oil: MS (ESI+) m/z 587.6 (M+H).
