Vorschrift

1.58 g (6.14 mmol) (4-allyloxy-phenyl)-methanethiol and 1.64 g (6.14 mmol) toluene-4-sulfonic acid 2-[1,2,3]triazol-1-yl-ethyl ester were dissolved in 15 ml DMF and cooled to −30° C. 294 mg (12.3 mmol) 95% Sodium hydride were added, the mixture allowed to warm to r.t. and stirred for 12 h. 10 ml Water were added and the residue dissolved in dichloromethane. The organic phase was dried over Na2SO4, solvents removed and the remaining material purified by chromatography on silica gel (ethyl acetate/n-heptane 1:1) to yield 1.33 g (79%) yellow oil.
