Procedimiento

Ethyl 2-(Formylaminothiazol-4-yl)-2-oxoacetate (9.1 g, 39.87 mmol) (obtained from Aldrich, Milwaukee, Wis.) was slurried in 50 mL of anhydrous DMF. N-Chlorosuccinimide (5.6 g, 41.86 mmol) was added as a solid and the suspension was stirred at room temperature. After 18 hours, the reaction mixture was poured into 500 mL of water. The resulting white precipitate was filtered, washed with water and air dried to afford the title intermediate as a white solid.
