Procedure
A suspension of 1.83 g of 3,5-dichloro-4H-1,2,6-thiadiazin-4-one in 100 ml of water is stirred mechanically at room temperature while a solution of 1.29 g of p-chlorophenol, 20 ml of H2O and 5 ml of 2N aqueous sodium hydroxide solution is added dropwise to it. The mixture is stirred an additional 1 hour. The resulting precipitate is collected and recrystallized from alcohol. The white crystals melt at 142°-145°. The compounds described in Table II can be prepared by the same procedure as Example 2 substituting the appropriate phenol for p-chlorophenol.
