Reaction Steps

To a 50 ml volume four-necked flask, 2-(2,6-diethyl-4-methylphenyl)-2-oxoacetic acid (8-a) (0.94 g), toluene (anhydrous) (3.0 ml) and dimethylformamide (anhydrous) (0.2 ml) were added under a nitrogen atmosphere and the internal temperature was raised to about 50° C. Thionyl chloride (0.45 ml) was added thereto and the resulting mixture was stirred at 50° C. for 2 hours. The mixture was concentrated under reduced pressure, and azeotropically distilled with toluene to give 0.96 g of 2-(2,6-diethyl-4-methylphenyl)-2-oxoacetyl chloride (6-a).
