Reaction Steps

A microwave vial charged with potassium phosphate (0.533 g, 2.51 mmol), 1-bromo-2-fluoro-4-(trifluoromethyl)benzene (0.610 g, 2.51 mmol) and 1 mL dioxane, was treated with morpholine (0.437 ml, 5.02 mmol) and was heated to 150° C. in a microwave reactor for one hour. LC/MS showed mostly starting material, so the reaction mixture was treated with 1 mL DMF and was heated to 150° C. in an oil bath overnight. LC/MS showed product, so the reaction mixture was diluted with DCM, filtered through a syringe filter, and concentrated. Purification of the resulting residue by silica gel column chromatography (0 to 50% EtOAc/heptane) gave 4-(2-bromo-5-(trifluoromethyl)phenyl)morpholine (0.280 g, 0.903 mmol) as a clear oil. [M+H]+=312.0
