Reaction Steps
In a 500-ml three-necked flask, 4 g (= 0.1 mole) of sodium hydroxide was dissolved at 60° C in 270 ml of methyl glycol, and 48.9 g of pentabromophenol was stirred in for the preparation of a phenolate solution, as in Example 8c. At 30° to 34° C, 18.9 g (- 0.1 mole) of o-chloromethylbenzoyl chloride was added drop by drop, with stirring, over a period of about 40 minutes, whereupon a white, crystalline preciptate settled out, which after 1 hour was suction filtered. After the product had been stirred up in water, suction filtered, washed and dried, 58 g (= 90.5%) of o-chloromethylbenzoic acid pentabromophenyl ester was obtained, which melted at 201°-205° C.
