Participants

Reaction Steps

A mixture of 3.66 g of 3,5-dichloro-4H-1,2,6-thiadiazin-4-one, 30 ml of ethyl ether, and 2.02 g of triethylamine is stirred at 0°-5° C. while a solution of 2.20 g of thiophenol in 20 ml of ethyl ether is added dropwise to it. This mixture is stirred 2 hours longer while it is allowed to return to ambient temperature. Then it is filtered to remove triethylamine hydrochloride, and the filtrate is concentrated on a rotary evaporator. The solid residue is recrystallized from hexane to yield yellow prisms, mp 100°-2°.
