実験手順
A mixture of 3,5-dichloro-4-methylbenzoic acid (230 g, 1.12 moles), thionyl chloride (204 g, 1.71 moles), and dimethylformamide (30 milliliters(ml), in toluene (1 liter) was slowly warmed to 70° C. and stirred at that temperature for 2 hours. The toluene was eliminated in the rotavap to yield 276 g of 3,5-dichloro-4-methylbenzoyl chloride, used in the next step as such.
