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 propionyl chloride (370 mg, 4.00 mmol). The crude product was purified by IFC (silica gel eluting with a gradient of 15 to 50% CMA in chloroform) followed by recrystallization from ethyl acetate/hexanes to provide 434 mg of N-{2-[4-amino-2-(methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-1-yl]-1,1-dimethylethyl}propionamide as a white solid, mp 157-158° C. MS (APCI) m/z 370 (M+H)+; Anal. Calcd for C20H27N5O2: C, 65.02; H, 7.37; N, 18.96. Found: C, 64.79; H, 7.58; N, 18.94.
