A mixture of 6-bromo-I-chlorophthalazine (Example 1, 0.245 g, 1 mmol), cyclohexanamine (0.22 g, 2 mmol) and potassium carbonate (0.14 g, 1 mmol) in 5 mL acetonitrile were added to a glass microwave reaction vessel. The reaction mixture was stirred and heated in a Smith Synthesizer® microwave reactor (Personal Chemistry, Inc., Upssala, Sweden) at 180° C. for 20 min. After 20 min., all starting material was converted to product (M+1=306, 308). The mixture was concentrated under vacuum, and purified via flash chromatography (silica gel) eluting with a gradient of 2% 2 M ammonia in MeOH/DCM to 6% 2 M ammonia in MeOH/DCM to give (0.21 g) 6-bromo-N-cyclohexylphthalazin-1-amine as a yellow solid. Found MS (ES+): 306, 308(M+H)+.
