Procedure
Using the general method of Example 599, 1-(2-amino-2-methylpropyl)-2-(2-methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-4-amine (500 mg, 1.60 mmol, prepared as described in Example 590) was reacted with 4-fluorobenzoyl chloride (634 mg, 4.00 mmol). The crude product was purified by IFC (silica gel eluting with a gradient of 5 to 20% CMA in chloroform) followed by recrystallization from ethyl acetate/hexanes to provide 551 mg of N-{2-[4-amino-2-(methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-1-yl]-1,1-dimethylethyl}-4-fluorobenzamide as a white solid, mp 187-189° C. MS (ESI) m/z 436 (M+H)+; Anal. Calcd for C24H26FN5O2: C, 66.19; H, 6.02; N, 16.08. Found: C, 65.92; H, 5.93; N, 15.87.
