Reaction Steps

To a solution of 7-bromo-2-hydrazinylquinoxaline (1.5 g, 0.063 mol) and 4-(2-cyanopropan-2-yl) benzoic acid (1.1 g, 0.063 mol) in DMF (5 mL) was added HATU (2.4 g, 0.063 mol) and DIEA (1.2 g, 0.095 mol). The reaction mixture was then stirred at r.t. overnight. The solution was diluted with water (5 mL), and the solid was collected on a filter to give N′-(7-bromoquinoxalin-2-yl)-4-(2-cyanopropan-2-yl)benzohydrazide as a yellow solid (2.2 g, yield 85.0%). MS (m/z): 412 (M+H)+.
