2-氨基-5-溴-N,3-二甲基苯甲酰胺

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 2-amino-5-bromo-3-methylbenzamide (820 mg, 3.55 mmol, 1.0 eq.) in THF (15 mL) and Et3N (0.7 nit) was added nicotinoyl chloride (551 mg, 3.91 mmol, 1.1 eq.) in anhydrous THF (15 mL) dropwise. The resulting mixture was stirred at room temperature overnight. After the reaction was completed, the resultant precipitate was filtered and dried in vacuo to give 1.74 g of crude iii-e as a yellow solid. LCMS m/z=333.8, 335.8 (M+1) (Method B) (retention time=1.42 min). the resultant precipitate was filtered dried in vacuo to give 1.74 g of crude iii-e as a yellow solid
