Procedure

Methanesulfonyl chloride (232 μL, 3.00 mmol) was added to a 0° C. stirred solution of 1-(2-amino-2-methylpropyl)-2-propyl-2H-pyrazolo[3,4-c]quinolin-4-amine (prepared as described in Example 64, 892 mg, 3.00 mmol) and triethylamine (627 μL, 4.5 mmol) in dichloromethane (26.7 mL). After 3 hours at 0° C., the solution was stirred for 2 days at ambient temperature. To the solution was added 2 M aqueous sodium carbonate. The mixture was extracted with chloroform four times. The organic layers were combined, dried over sodium sulfate, filtered, and concentrated under reduced pressure to yield a white solid. The crude product was purified by IFC (silica gel, elution with 10% CMA in chloroform). The appropriate fractions were combined and concentrated under reduced pressure to provide a white foam that was crystallized from acetonitrile, isolated by filtration, and dried to yield 600 mg of N-[2-(4-amino-2-propyl-2H-pyrazolo[3,4-c]quinolin-1-yl)-1,1-dimethylethyl]methanesulfonamide as a white solid, mp 130-139° C.
