Reaction Steps
216.46 g (2.74 mols) of pyridine was slowly added to a solution containing 467.5 g (2.61 mols) of 2-methyl-6-(1-methyl-1-methoxyethyl)-aniline in 2.74 liters of methylene chloride at room temperature (about 18°-25° C.). 309.62 g (2.74 mols) of chloroacetyl chloride was added dropwise over a 20-minute period. The temperature of the mixture was maintained at about, or less than, 25° C. during this addition. The mixture was then stirred at about 18° C. for about 1 hour and then mixed with two liters of water. The methylene chloride phase was then separated treated with aqueous 5 wt. % hydrochloric acid until slightly acidic and then washed with water and dried over magnesium sulfate. The mixture was then evaporated to dryness affording a brownish solid which was then washed with a 10% isopropanol:90% hexane mixture affording 484 g of the title compound.
