Versuchsvorschrift

A suspension consisting of 21.2 g. of α,α'-bis(2-chloroethylsulfonyl)-p-xylene (prepared from p-xylylene dichloride as in Example 1), 25 ml. of triethylamine, 0.05 g. of hydroquinone and 400 ml. of ethyl acetate-N,N-dimethylformamide (1:1 v./v.) were stirred at 25° C. for 20 hours and filtered. The filtrate was evaporated to 150 ml. volume, poured into water and the white solid isolated and recrystallized from methanol and ethyl acetate; m.p. 207°-212° C.
