실험 절차
A solution of 1.50 g (4.5 mmol) tert-butyl [3-methyl-3-(6-methyl-2-oxo-2,3-dihydro-benzimidazol-1-yl)-butyl]-carbamate in 100 mL dioxane is combined with 10 mL 4 molar hydrochloric acid in dioxane and then heated to 90° C. for 90 minutes, during which time a white precipitate settles out. After cooling to ambient temperature the solvent is distilled off and the residue is stirred in diethyl ether. White solid. Yield: 1.04 g (86%; hydrochloride); mass spectroscopy: [M+H]+=234.
