Procedure

N-(aminocarbonothioyl)-3-chloro-2-methylbenzenesulfonamide (0.4 g, 1.5 mmol) and methyl 3-bromo-4-oxobutanoate (0.3 g, 1.5 mmol), dissolved in pyridine (5 mL), were irradiated in a microwave oven for 2.5 min at 130° C. The solvent was removed under reduced pressure and the product separated from the starting materials using preparative HPLC (yield 0.2 g, 30%).
