Into a mixed solvent of 80 ml of 40% methylamine and 600 ml of ethanol, 13.9 g of ethyl 2-(2-methoxyphenyl)-4-methylthiazole-5-carboxylate was dissolved. Then, in a similar manner in Example 1, the object was obtained as colourless aciculate melting at 167.5° to 168.5° C. in an amount of 9.4 g corresponding to the yield of 72%.
