Upon complete reaction of the starting materials, 20 mmol ammonium chloride was added, to carry out reaction in closed state for 12 hr. The reaction product was filtered to remove inorganic salt, and then the resultant filtrate was concentrated to obtain 2-acetylamino-4-thiazolformamidine hydrochloride.
