Procedure
To a solution of 2-amino-5-chlorothiazole hydrochloride (2.62 g, 15.3 mmol, 3 eq) in pyridine (10 ml) was added methyl 4-(chlorosulfonyl)-2-chlorobenzoate (2.28 g, 5.1 mmol, 1 eq) portionwise and the reaction mixture stirred at room temperature for 1 hour. The solution was added to 6M HCl (40 ml) and the resultant precipitate collected by filtration. The crude material was triturated with t-butylmethyl ether to yield the title compound (410 mg, 1.1 mmol, 22%).
