実験手順

A solution of (1R)-1-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)-2-{[(1S)-2-hydroxy-1-phenylethyl][6-(4-phenylbutoxy)hexyl]amino}ethanol (110 mg), in ethanol (75 ml), was hydrogenated over Pearlman's catalyst [Pd(OH)2, 60% H2O, 55 mg) for 18 h. The catalyst was removed by filtration and the residue was washed with methanol. The combined filtrate and washings were concentrated and then applied to a 10 g SCX ion exchange cartridge. The cartridge was eluted with methanol (4 column volumes) and then with 10% aqueous 880 NH3 in methanol (3 column volumes). The ammoniacal eluent was concentrated under reduced pressure to give the title compound (69 mg) as a colourless oil.
