Procedure

To a solution of N-[2-(5-butyl-1-tert-butyl-3-cyano-1H-pyrazol-4-yl)phenyl]-2,2-dimethylpropanamide (1.63 g, 4.28 mmol) in ethanol was added sodium tert-butoxide (0.494 g, 5.14 mmol). The solution was heated at reflux for 1 day, then was allowed to cool to ambient temperature. A precipitate formed that was isolated by filtration and washed with a small amount of water (24 mL) and ethanol (3 mL) to yield 0.4667 g of 1-butyl-2-tert-butyl-2H-pyrazolo[3,4-c]quinolin-4-amine as off-white crystals, mp 222.0-223.0° C.
