実験手順

The title compound was synthesized as described for compound 9 using (2R,3R,4R)-3,4-dibenzyloxy-2-benzyloxymethyl-1-butylpyrrolidine (Compound 10) (0.243 g,0.53 mmol), ethanol (30 ml), 10% Pd/C (0.07 g) and excess of 1 M hydro-chloric acid to convert the amine to the hydrochloride salt. (2R,3R,4R)-1-Butyl-3,4-dihydroxy-2-hydroxymethylpyrrolidine, hydrochloride was obtained as a yellow syrup (0.098 g, yield: 82%).
