Versuchsvorschrift

To an ice-cooled solution of [2-(4-iodo-2-methyl-imidazol-1-yl)-ethyl]-carbamic acid tert-butyl ester (2.800 g; 7.973 mmol) in DCM (45 ml) was added slowly 4N HCl in dioxane (28.25 ml; 113.000 mmol). The resulting suspension was stirred at 0° C. for 15 min., then at rt for 1 h. The volatiles were removed under reduced pressure, then under HV. The product 2-(4-iodo-2-methyl-imidazol-1-yl)-ethylamine was obtained as a pale beige solid (2.880 g; 100%; presence of 3 eq. of HCl). LC-MS: tR=0.14 min.; [M+H]+=251.92 g/mol.
