Reaction Steps

3-(3-{[7-(Benzyl{(2R)-2-hydroxy-2-[4-hydroxy-3-(hydroxymethyl)phenyl]ethyl}amino)heptyl]oxy}propyl)benzenesulfonamide (87.2 g) in methanol (800 ml) was hydrogenated over 5% Pd/C catalyst (28 g, 50% wet) at atmospheric pressure and ambient temperature. The catalyst was removed by filtration through a Hyflo pad and the filtrate concentrated in vacuo to give the title compound (64.4 g)—LC RT=3.46 min. δ (DMSO-d6)—7.65 (2H,m), 7.45 (2H, m), 7.25 (1H, s), 6.95 (1H, dd, J 8, 2 Hz), 6.67 (1H, d, J 8 Hz), 5.0 (2H, br m,), 4.45 (3H, m), 3.35 (4H, m), 3.15 (2H, m), 2.7 (2H, m), 2.55-2.45 (4H, m), 1.8 (2H, m), 1.5 (2H, m), 1.35 (2H, m), 1.25 (6H, m).
