Procedure

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.
