Procedure

Using the method of Example 68, 1-(2-amino-2-methylpropyl)-2-propyl-2H-pyrazolo[3,4-c]quinolin-4-amine (prepared as described in Example 64, 595 mg, 2.00 mmol) was reacted with propionyl chloride (463 mg, 5.00 mmol). The crude product was purified by IFC (silica gel eluting with a gradient of 15 to 25% CMA in chloroform) followed by recrystallization from ethyl acetate/hexanes to provide 545 mg of N-[2-(4-amino-2-propyl-2H-pyrazolo[3,4-c]quinolin-1-yl)-1,1-dimethylethyl]propionamide as a white solid, mp 158-159° C. MS (APCI) m/z 354 (M+H)+; Anal. Calcd for C20H27N5O: C, 67.96; H, 7.70; N, 19.81. Found: C, 67.80; H, 8.08; N, 19.77
