Bromoacetyl chloride (0.211 ml, 2.52 mmol) was added and the reaction let stir at rt for 40 min. LCMS analysis indicated complete conversion to the acyl bromide so a 2M solution of dimethylamine in THF (4.6 ml, 9.15 mmol) was added and let stir at rt overnight. The reaction was diluted with EtOAc and washed with a saturated brine solution. Aqueous layers were re-extracted with EtOAc. Organics were combined and dried over sodium sulfate and filtered. Solvents were removed under reduced pressure to afford N2,N2-dimethyl-N1-[2-methyl-4-(methyloxy)-5-nitrophenyl]glycinamide (0.642 mg, 2.4 mmol). ESIMS (M+H)+=268.
