To a well-stirred solution of 1.1 g (13.1 mmol) sodium bicarbonate in 15 mL water was added solid 3-amino-1-chloro-3-methyl-2-pentanone hydrochloride (1 g, 5.4 mmoles) portionwise. To the resulting solution was added 15 mL of hexane followed by dropwise addition of a solution of 3,5-dichloro-4-methylbenzoyl chloride (1.2 g, 5.4 mmol) in 1 mL of tetrahydrofuran. Another 15 mL of hexane was added, and the resulting mixture was stirred at room temperature for 2 hours. The reaction mixture was filtered, and the resulting white solid was dried in a vacuum oven yielding 1.1 g of 3,5-dichloro-N-(3-chloro-1-ethyl-1-methyl-2-oxopropyl)-4-methylbenzamide as a white solid (mp 159-161° C.).
