Participants

Reaction Steps

To a degassed solution of tris(dibenzylideneacetone) dipalladium(0) (7 mg, 0.007 mmol) and 2-(di-tert-butylphosphino)biphenyl (6 mg, 0.021 mmol) in toluene (2 mL) was added N-(t-butoxycarbonyl)-(R)-1,3,4,10b-tetrahydro-9-bromo-7-trifluoromethyl-pyrazino[2,1-a]isoindol-6(2H)-one (50 mg, 0.115 mmol). The mixture was degassed (alternating vacuum and argon) and aniline (0.031 mL, 0.345 mmol) and sodium tert-butoxide (33 mg, 0.345 mmol) were added. The mixture was degassed a final time and then subjected to microwave conditions (150° C., 1800 sec). The mixture was diluted with saturated aqueous sodium chloride and ethyl acetate, and the layers were separated. The aqueous layer washed with ethyl acetate (×2) and the combined organic layers were dried over sodium sulfate, filtered, and concentrated. The resulting residue was purified by radial chromatography (10-20% ethyl acetate in hexanes) to give 28 mg (55%) of a pale yellow residue. MS (ESI) 448 (M+H).
