Reaction Steps

At a temperature and in the manner as described in Example 1, 39 g of potassium thiocyanate (0.4 mol) and 38.5 g of resorcinol (0.35 mol) are stirred with 0.3 l of 98% hydrofluoric acid, and subsequently, the mixture is stirred for 5 hours at room temperature. 0.25 l of hydrofluoric acid are then distilled off, and the residue is mixed with a small amount of ice, which causes 47 g of 2,4-dihydroxy-thiobenzamide to crystallize. This corresponds to a yield of 80% of the theoretical yield, relative to the resorcinol used. The melting point is 164° - 166° C.
