Participants

Reaction Steps

To a solution of 0.39 g (0.74 mmol) of 2-[(4-but-3-enyloxy-benzenesulfonyl)-(4-imidazol-1-yl-benzyl)-amino]-N-(1-methoxy-1-methyl-ethoxy)-acetamide (stage 80.4), 2.46 ml of 6 N aqueous hydrochloride is added at r.t. After being stirred for 15 min, the reaction mixture is neutralized with sat. NaHCO3 and extracted with AcOEt. The combined extracts are washed with brine, dried over MgSO4 and concentrated under reduced pressure to give 2-[(4-but-3-enyloxy-benzenesulfonyl)-(4-imidazol-1-yl-benzyl)-amino]-N-hydroxy-acetamide as a colorless powder. To a solution of 0.17 g (0.37 mmol) of the above prepared hydroxy acetamide in 3 ml of dioxane, 0.447 ml of 1 N aqueous hydrochloride is added and stirred for 10 min. The reaction mixture is concentrated under reduced pressure and dried in vacuo to give ther title compound. 1H-NMR (400 MHz, DMSO-d6): 2.40–2.50 (m, 2H), 3.61 (s, 2H), 4.07 (t, 2H, J=6.52 Hz), 4.37 (s, 2H), 5.00–5.15 (m, 2H), 5.75–5.90 (m, 1H), 7.04 (d, 2H, J=8.56 Hz), 7.48 (d, 2H, J=8.56 Hz), 7.65–7.75 (m, 5H), 7.81 (s, 1H), 8.19 (s, 1H), 9.57 (s, 1H), 10.54 (brs, 1H).
