Reaction Steps

A solution of 0.22 g of 2-{[4-(4-fluorobutoxy)-benzenesulfonyl](4-methoxy-benzyl)amino}-N-(1-ethoxy-1-methyl-ethoxy)acetamide in 30 ml of AcOEt is treated with 7 ml of 5N aqueous HCl for 10 min. at r.t. and the mixture is extracted with AcOEt. The combined extracts are washed with sat. NaHCO3 and brine, dried over MgSO4 and concentrated under reduced pressure to give solids which are washed with ether to afford 2-{[4-(4-fluorobutoxy)-benzenesulfonyl]-(4-methoxy-benzyl)amino]-N-hydroxy-acetamide; NMR (CDCl3): 1.83-2.05 (m, 4H), 3.69 (s, 2H), 3.78 (s, 3H), 4.09 (t, 2H, J=5.56 Hz), 4.25 (s, 2H), 4.48 (t, 1H, J=5.52 Hz), 4.55-4.65 (m, 1H), 6.84 (d, 2H, J=8.56 Hz), 7.00 (d, 2H, J=9.04 Hz), 7.02 (br s, 1H), 7.15 (d, 2H, J=8.56 Hz), 7.77 (d, 2H, J=8.56 Hz), 8.85 (br s, 1H).
