実験手順

To a solution of 3-{[6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carbonyl]-amino}-3-hydroxymethyl-pyrrolidine-1-carboxylic acid tert-butyl ester (55 mg) in DCM (2 mL) was added 4 N HCl in dioxane (1.0 mL) at 0° C., and the reaction was stirred for 1 h at room temperature. The volatiles were removed under reduced pressure, and the residue was triturated with anhydrous ethyl ether and dried under high vacuum to provide 6-butyl-5-(4-cyclohexyloxy-phenyl)-pyridazine-3-carboxylic acid (3-hydroxymethyl-pyrrolidin-3-yl)-amide dihydrochloride.
