실험 절차

Methyl 4-(chlorosulfonyl)benzoate (Preparation 2, 8.0 g, 34 mmol, 1 eq) was added portionwise to a solution of 2-amino-5-chlorothiazole hydrochloride (23.3 g, 136 mmol, 4 eq) in pyridine (80 ml) and the reaction mixture stirred at room temperature for 1 hour. The solution was added to a stirred solution of 6M HCl (300 ml) and the resulting precipitate collected by filtration and washed with water. The title compound was obtained as a dark brown solid (3.35 g, 0.01 mmol, 30%).
