Procedure

2-Bromo-N-(2-tert-butyl-5-nitrophenyl)acetamide (80 g, 253, mmol) and potassium carbonate (70 g, 506 mmol) were combined in THF (1.75 L), and the mixture was cooled to 0° C. N,N-Dimethylamine (40 ml of a 2 M solution in THF, 800 mmol) was then added to the mixture through an addition funnel over a 30-min period. The mixture was then stirred at RT for 16 h. The mixture was then filtered and the filtrate was concentrated. The crude material was purified by silica chromatography using 50% EtOAc:hexanes as the eluent to give N-(2-tert-butyl-5-nitrophenyl)-2-(dimethylamino)acetamide as a brown solid.
