Reaction Steps
A mixture of 2-chlorothiazole (2.0 g), ethyl 4-hydroxybenzoate (2.8 g), potassium carbonate powder (3.5 g) and dimethylformamide (30 ml) is stirred at 135°-140° C. for 6 hours. The reaction mixture is treated in the same manner as in Example 1. From the eluate of 30% ether-benzene, ethyl 4-(2-thiazolyloxy)benzoate (1.16 g) is obtained. IR νmaxCCl4 1730, 1280 cm-1.
