Procedure

Using 3.7 g of 4-benzyloxy-2-methylnaphthol, 1.4 g of anhydrous potassium carbonate, 5.0 g of chloromethyloxirane, 2.2 g of 1-(2-tolyl)piperazine hydrochloride and 1.2 g of triethylamine, reaction was carried out as in Examples 1-A and 2. The thus obtained crystals were recrystallized from ethanol-isopropyl ether to give 2.3 g, m.p. 261-263° C. (decomp.).
