実験手順
A solution of (S)-4-{2-[2-hydroxy-3-(4-benzyloxyphenoxy)propylamino]ethyl}phenoxymethylcyclohexylphosphinic acid, n-butyl ester (1.00 g, 1.64 mMol) in methanol (100 ml) containing 10% palladium on charcoal (50 mg) was hydrogenated at 40° C. and 40 p.s.i. for 24 hours. After cooling to room temperature the suspension was filtered through a pad of filter aid and the filtrate was evaporated giving the title compound.
