A mixture of methyl 3-bromo-5-nitrobenzoate (5 g, 19.23 mmol), morpholine (1.76 mL, 20.19 mmol), tris(dibenzylideneacetone)dipalladium (0) (1.32 g, 1.442 mmol), XPhos (1.38 g, 2.88 mmol), tripotassium phosphate (5.71 g, 26.9 mmol), and toluene (38.5 mL) was stirred overnight at 95° C. under nitrogen. Upon completion, the reaction was cooled to 23° C. and filtered over Celite. The filtrate was concd, and the crude material was purified by column chromatography (silica; 0-30% EtOAc in hexanes) to afford methyl 3-morpholino-5-nitrobenzoate as an orange amorphous solid. Mass Spectrum (ESI) m/e=267.2 (M+1).
