Reaction Steps

4-(4,6-Dimethoxy-1,3,5-triazin-2-yl)-4-methylmorpholinium chloride n-hydrate (n=about 2.7) (2.42 g, 7.53 mmol) was added to a mixture of 4-bromo-3-methylbenzoic acid (1.58 g, 7.37 mmol), EtOH (26 ml) and a 40% aqueous dimethylamine solution (0.75 ml, 7.4 mmol), and the mixture was stirred at room temperature for 24 hours. The reaction mixture was concentrated under reduced pressure, and the resulting residue was then dissolved in ethyl acetate. The organic layer was washed with water, and then dried over MgSO4 and concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to give 4-bromo-3,N,N-trimethyl-benzamide as a colorless solid (1.16 g, 65%).
