Procedure

To a solution of 2 g (7.683 mmol) of (4-[1,2,4] triazol-1-yl-benzylamino)-acetic acid ethyl ester in 15 ml of dioxane and 15 ml of H 20, 2.3 g (9.22 mmol) of 4-but-3-enyloxy-benzenesulfonyl chloride and 1.3 ml (9.22 mmol) of triethyl amine are successively added at 0–5° C. After being stirred for 18 h at r.t., the reaction mixture is diluted with H 20 and extracted with AcOEt. The combined extracts are washed with brine, dried over MgSO4 and concentrated under reduced pressure. The residue is purified by column chromatography on silica gel to give the title compound. 1H-NMR (400 MHz, CDCl3): 1.17 (t, 3H, J=7.04 Hz), 2.55–2.65 (m, 2H), 3.95 (s, 2H), 4.07 (t, 2H, J=7.04 Hz), 4.09 (t, 2H, J=6.56 Hz), 4.53 (s, 2H), 5.10–5.25 (m, 2H), 5.85–5.95 (m, 1H), 6.99 (d, 2H, J=8.04 Hz), 7.44 (d, 2H, J=7.56 Hz), 7.64 (d, 2H, J=8.04 Hz), 7.82 (d, 2H, J=7.56 Hz), 8.11 (s, 1H), 8.55 (s, 1H).
