Reaction Steps

A mixture of thiosalicylic acid (44 g), 5-chloro-1,3-dimethoxybenzene (49.2 g), potassium carbonate (78 g), copper (powder) (4.3 g) and copper(I) iodide (4.3 g) in N-methyl-2-pyrrolidone (390 ml) was stirred at 190° C. for 10 hours. The reaction mixture was treated by the same procedure as in Example 1 to give 8.0 g (10%) of a compound of the indicated formula (10).
