To a solution of 10.4 g (66.9 mmol) 1,3-dimethyl-pyrimidine-2,4,6-trione and 774 mg (0.67 mmol) tetrakis-(triphenylphosphine)-palladium in 100 ml dichloromethane was added dropwise a solution of 6.18 g (22.3 mmol) 1-[2-(4-allyloxy-2-fluoro-benzyloxy)-ethyl]-1H-[1,2,3]triazole in 30 ml dichloromethane and stirring was continued for 24 hours at 40° C. It was allowed to cool down over night. The reaction mixture was extracted with three 100 ml portions of sodium bicarbonate solution, the organic extract was dried, evaporated and purified by chromatography on silica (ethyl acetate/dichloromethane 3:7) to yield 2.97 g (56%) 3-fluoro-4-(2-[1,2,3]triazol-1-yl-ethoxymethyl)-phenol as oil.
