Reaction Steps
ethyl 5-bromonicotinate (200 mg, 0.87 mmol), morpholine (0.083 mL, 0.96 mmol), sodium 2-methylpropan-2-olate (167 mg, 1.74 mmol), 2'-(dicyclohexylphosphino)-N,N-dimethylbiphenyl-2-amine (17.11 mg, 0.04 mmol) and TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0) (19.90 mg, 0.02 mmol) were suspended in dioxane (5 mL) and sealed into a microwave tube. The reaction was heated to 100 °C for 1 hour in the microwave reactor and cooled to RT. LCMS analysis appeared to indicate addition of 2 morpholine rings and the reaction was abandoned.
