A suspension of 101 g. (0.326 mole) of 1-(2,6-dibromophenyl)thiourea in 1 l. of chlorobenzene was stirred and refluxed 20 hours, and the resulting solution was filtered and evaporated. The tan solid obtained was triturated with boiling petroleum ether and filtered. On cooling, the filtrate deposited 63.4 g. of yellow needles of 2,6-dibromophenylisothiocyanate, m.p. 63°-65°. A portion was recrystallized from ether-petroleum ether to give the analytical sample, m.p. 65°-66°.
