Reaction Steps

To a solution of 8.3 g (26 mmol) of ethyl 2-(2,4,5-trifluoro-6-methylbenzoyl)-3-ethoxyacrylate in 30 mL of absolute ethanol at 5° C. was added 1.64 g (29 mmol) of cyclopropylamine. The reaction mixture was stirred at 5° C. for 90 minutes and at room temperature for 2 hours. The solution was concentrated to give a brown oil which was dissolved in hexane and reconcentrated to give a tan solid. Recrystallization from hexane gave 7.2 g of colorless crystals, mp 69°-72° C.
