Hydrochloric Acid → 1-Oxazol-4-yl-ethylamine dihydrochloride

Participants

Reaction Steps

In a round-bottomed flask, 2-methyl-propane-2-sulfinic acid (1-oxazol-4-yl-ethyl)-amide (585 mg, 2.57 mmol) was dissolved in methanol (4.5 ml) and hydrogen chloride (4.0 M in 1,4-dioxane, 1.3 ml, 5.2 mmol) was added dropwise. The reaction mixture was stirred at room temperature for 15 min then concentrated to give 1-oxazol-4-yl-ethylamine dihydrochloride as a viscous orange oil which was used without further purification.
