A microwave vial was charged with 5-bromo-2-iodo-N,N-dimethyl-benzamide (200 mg, 0.74 mmol), 2-oxazolidinone (77.4 mg, 0.89 mmol), copper(I)-iodide (70.5 mg, 0.04 mmol), trans-1,4-cyclohexanediamine (84.6 mg, 0.74 mmol), and potassium phosphate (377.2 mg, 1.78 mmol) and degassed dioxane (2 ml) added. The reaction mixture was irradiated to 150° C. for 1 hour in a microwave reactor. The solvent was evaporated and the resulting solid purified by silica gel chromatography to give 5-bromo-N,N-dimethyl-2-(2-oxo-oxazolidin-3-yl)-benzamide as a white solid (150 mg, 65% yield). MS: m/z 315.4 (M+H+).
