Procedure

5% Pd/C (8 g, 50% wet) was added to a solution of 3-(4-{[6-(Benzyl{(2R)-2-hydroxy-2-[4-hydroxy-3-(hydroxymethyl)phenyl]ethyl}amino)hexyl]oxy}butyl)benzenesulfonamide (16 g) in IMS and the mixture was stirred under hydrogen for 6 h. The resulting suspension was filtered through a plug of Celite which was then washed with IMS (160 ml). The combined washings were concentrated under reduced pressure to give the title compound (12.8 g) as an oil, LC RT=3.51 min, δ (CD3OD) 7.64 (1H, s), 7.61 (1H, m), 7.33 (2H, m), 7.20 (1H, s), 7.01 (1H, dd, J 2.2, 8.2 Hz), 6.65 (1H, d, J 8.2 Hz), 4.61 (1H, m), 4.54 (2H, s), 3.33 (4H, m), 2.72 (2H, m) 2.63 (2H, m), 2.57 (2H, m) 1.62 (2H, m), 1.46 (6H, m), 1.27 (4H, m).
