944804-88-0, tert-Butyl 4-bromothiazol-2-ylcarbamate is a thiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
4-Methoxybenzyl chloride (2.72 mL, 20.09 mmol) was added to a solution of terEbutyl (4-bromothiazol- 2-yl)carbamate (5.10 g, 18.26 mmol) and CS2CO3 (11.90 g, 36.53 mmol) in DMF (40 mL) and the mixture was stirred at 80 C for 1 h. The reaction mixture was cooled to 25 C, quenched with water (100 mL), and extracted with EtOAc (3 x 300 mL). The organic extracts were dried over MgSCL, filtered, and concentrated under reduced pressure. The residue was purified by column chromatography (hexane: EtOAc; 1 :0 to 9.5:0.5) to afford the product (7.20 g, 99%) as a pale yellow wax.
