Procedure

The method described in Example 1254 was used to treat 1-(4-chlorobutyl)-2-(2-methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-4-amine (1.1 g, 3.3 mmol) with methanesulfonamide pretreated with sodium hydride in the presence of sodium iodide. The crude was purified by chromatography using a HORIZON HPFC system (40+M cartridge, eluting with 0-30% CMA in chloroform) followed by recrystallization from acetonitrile to provide 600 mg of N-{4-[4-amino-2-(2-methoxyethyl)-2H-pyrazolo[3,4-c]quinolin-1-yl]butyl}methanesulfonamide as white crystals, mp 159-161° C.
