Reaction Steps

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-minute period. The mixture was then stirred at room temperature for 16 hours. The mixture was filtered and the filtrate concentrated. The crude material was purified by silica chromatography eluting with 50% EtOAc:hexanes to give N-(2-tert-butyl-5-nitrophenyl)-2-(dimethylamino)acetamide as a brown solid.
