Procedure
To a 0° C. stirred solution of 0.54 g (1.32 mmol)N2-(tert-butoxycarbonyl)-N5-(iminoisopropoxymethyl)-L-ornithine tert-butyl ester hydrochloride in 2 ml dioxane was added 10 mL of 4N hydrochloric acid in dioxane solution. The solution was stirred 14 h leaving a pale yellow precipitate. The dioxane was removed under reduced pressure and the residue suspended in ether. After stirring for 3 h, the ether was decanted and the solids dried under vacuum to give 0.52 g N5-(iminoisopropoxymethyl)-L-ornithine dihydrochloride. TLC (silica gel, ammonium hydroxide:methanol/1:25) Rf=0.27.
