Procedure

In a round-bottomed flask, 2-methyl-propane-2-sulfinic acid (1-oxazol-2-yl-ethyl)-amide (449 mg, 1.97 mmol) was dissolved in methanol (3.5 ml) and hydrogen chloride (4.0 M in 1,4-dioxane, 1.0 ml, 4.0 mmol) was added dropwise. The reaction mixture was stirred at room temperature for 15 min then concentrated to give 417 mg of 1-oxazol-2-yl-ethylamine dihydrochloride as an orange waxy solid which was used without further purification.
