Reaktionsschritte

A suspension of 1.50 g (6.3 mmol) 4-chloromethyl-2-(4-methoxy-phenyl)-thiazole, 0.65 g (9.4 mmol) 1H-[1,2,3]triazole, 0.11 g (0.63 mmol) potassium iodide and 0.37 g (9.4 mmol) sodium hydroxide in 20 ml 2-methyl-2-butanol was stirred at 120° C. for 5 h. After evaporation, the residue was quenched with water and extracted with ethyl acetate. The extract was dried and concentrated to yield 1.4 g (82%) 1-[2-(4-methoxy-phenyl)-thiazol-4-ylmethyl]-1H-[1,2,3]triazole as beige crystals, melting at 89-94° C.
