Procedure
In a 250 mL round-bottomed flask, 2-methyl-propane-2-sulfinic acid [1-(1-methyl-1H-imidazol-2-yl)-ethyl]-amide (700 mg, 3.05 mmol) was combined with methanol at 0° C. to give a colorless solution. Hydrogen chloride (4.0 M in 1,4-dioxane, 10 ml, 40.0 mmol) was added. The reaction mixture was stirred at 0° C. for 2 h then concentrated in vacuo to provide 1-(1-methyl-1H-imidazol-2-yl)-ethylamine dihydrochloride. 1H NMR (300 MHz, DMSO-d6): δ 9.28 (bs, 1H), 7.67 (bs, 2H), 4.92 (bs, 1H), 3.93 (bd, 1H), 1.67 (bd, 3H).
