Procedure

A mixture of 14.1g (0.08 mole) of 1-thiacyclooctane-5-one 1,1-dioxide and 16.1g (0.086 mole) of p-bromophenylhydrazine in 125 ml of glacial acetic acid is treated according to the procedure in Example 2. There is obtained 14.2g (54%) of a buff solid, m.p. 280° C., dec. Recrystallization from dimethylformamide-methanol gives 11.5g (44%) of an analytical sample, m.p. 283° C., dec.
