Vorschrift

(R)-3-t-butyloxycarbonylamino-1-carbomethoxymethyl-3,4-dihydrocarbostyril (20 mg) was dissolved in 4 M hydrogen chloride in 1,4-dioxane solution (5 mL) at room temperature. After 1 h the solvent was evaporated under vacuum, and the residue was twice taken up in toluene (10 mL) and evaporated under vacuum to provide (R)-3-amino-1-carbomethoxymethyl-3,4-dihydrocarbostyril hydrochloride, a white solid (21 mg).
