Procedure

Using the general method of Example 599, 1-(2-amino-2-methylpropyl)-2-(2-methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-4-amine (0.52 g, 1.66 mmol, prepared as described in Example 590) was reacted with 3,4-difluorobenzoyl chloride. The crude product was purified as described in Example 599 to provide 382 mg of N-{2-[4-amino-2-(methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-1-yl]-1,1-dimethylethyl}-3,4-difluorobenzamide as a white solid, mp 199-200° C. MS (ESI) m/z 454 (M+H)+; Anal. Calcd for C24H25F2N5O2: C, 63.57; H, 5.56; N, 15.44. Found: C, 63.37; H, 5.50; N, 15.58.
