実験手順

Methanesulfonic anhydride (0.34 g, 1.93 mmol) was added to a stirred solution of N-{2-[4-amino-7-[(6-aminohexyl)oxy]-2-(ethoxymethyl)-1H-imidazo[4,5-c]quinolin-1-yl]-1,1-dimethylethyl}-N′-isopropylurea (prepared as described in Parts A-H of Example 369, 10.9 g, 1.75 mmol) and triethylamine (0.35 mL, 3.5 mmol) in dichloromethane (50 mL) at 0° C. After approximately 30 minutes, the solution was allowed to warm to room temperature and was stirred overnight. The following morning, the solution was cooled to 0° C. and additional methanesulfonic anhydride (0.13 g) was added. After 30 minutes, the solution was allowed to warm to room temperature. After 2 hours, the solution was transferred to a separatory funnel and washed with water (2×) and brine. The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure. The crude product was purified by flash chromatography (silica gel, elution with 10% methanol in dichloromethane) followed purification by chromatography on a HORIZON HPFC system (an automated, modular high-performance flash purification product available from Biotage, Inc, Charlottesville, Va., USA) (silica gel, gradient elution with 0-40% CMA in chloroform where CMA is a solution of 80:18:2 chloroform/methanol/concentrated ammonium hydroxide) to yield 0.31 g of N-(6-{[4-amino-2-(ethoxymethyl)-1-(2-{[(isopropylamino)carbonyl]amino}-2-methylpropyl)-1H-imidazo[4,5-c]quinolin-7-yl]oxy}hexyl)methanesulfonamide as an off white solid, mp 190-194° C.
