Procedure

In a manner similar to that described above, but starting from 45.2 g (0.2 mole) of 1-(2-naphthylmethyl)-piperazine and 12 g (0.1 mole) of 2-chlorothiazole in 150 ml of dimethylformamide at 150° C., there were obtained 17 g of 1-(2-naphthylmethyl)-4-(2-thiazolyl)-piperazine as beige crystals melting at 83°-84° C.
