Reaction Steps

1H-Indazol-4-amine (81 mg, 0.61 mmol) and methyl 3-iodobenzoate (160 mg, 0.61 mmol) were dissolved in DMF (1 mL) in a microwave tube. Copper (I) iodide (23 mg, 0.12 mmol), trans-N,N′-dimethyl-1,2-cyclohexanediamine (34 mg, 0.24 mmol) and potassium carbonate (169 mg, 1.22 mmol) were added and the mixture heated by microwave (250 W) at 100° C. for 20 minutes. The mixture was filtered through a cartridge, washing with DCM (5 mL) and the filtrate was evaporated to dryness and purified by mass-directed autopreparation. The appropriate fractions were evaporated, dissolved in DCM (10 mL), washed with aqueous sodium bicarbonate, and evaporated to give the title compound (32.7 mg).
