Reaction Steps
3-bromo-5-(trifluoromethyl)pyridine (100 mg, 0.44 mmol), methylamine hydrochloride (59.8 mg, 0.88 mmol), and cesium carbonate (490 mg, 1.50 mmol) were suspended in dioxane (3 mL) . The reaction was purged with nitrogen for 30 minutes then 9,9-Dimethyl-4,5-bis(diphenylphosphino)xanthene (7.68 mg, 0.01 mmol) and TRIS(DIBENZYLIDENEACETONE)DIPALLADIUM(0)-CHLOROFORM ADDUCT (9.16 mg, 8.85 µmol) were added. The reaction was heated to 130 °C in a CEM microwave for 1 hour. No Product formed. Abandoned
