Reaction Conditions

Reaction Steps

A glass microwave reaction vessel was charged with nipecotamide (0.17 g, 1.4 mmol), 6-bromo-1-chlorophthalazine (0.110 g, 0.45 mmol), potassium carbonate (0.062g, 0.45 mmol) and 3 mL acetonitrile. The reaction mixture was stirred and heated in a Smith Synthesizer® microwave reactor (Personal Chemistry, Inc., Upssala, Sweden) at 190° C. for 20 min (watts, Powermax feature on, ramp time 1 min). The mixture was purified directly via flash chromatography (silica gel) eluting with 4/1 hexanes/EtOAc to 4/1 hexanes/EtOAc to give (0.15 g) 1-(6-bromophthalazin-1-yl)piperidine-3-carboxamide as a white solid. Found MS (ES+): 335, 337(M+H)+.
