To a solution of 100 mg of 5-bromo-2-(1-cyclopentyl-1H-pyrazol-5-yl)aniline in 2.5 mL of N-methylpyrrolidone was added 105 mg of CDI, followed by stirring at 150° C. for 2 hours using a microwave reactor, and cooling to room temperature. The precipitated solid was collected by filtration, washed with ethyl acetate, and then dried under reduced pressure to obtain 73 mg of 7-bromo-1-cyclopentyl-1,5-dihydro-4H-pyrazolo[4,3-c]quinolin-4-one.
