실험 절차

Triethylamine (1.93 mL, 5 eq) was added to a chilled (ice/water bath) suspension of N-[4-(4-amino-2-ethyl-1H-imidazo[4,5-c]quinolin-1-yl)butyl]methanesulfonamide (1.0 g, 1 eq) in NMP (6.0 mL). Propyl chloroformate (1.02 g, 3 eq) was added dropwise. The reaction mixture was allowed to come to ambient temperature and stirred for 24 hours. The reaction mixture was diluted with cold water (25 mL) and then extracted with dichloromethane (50 mL). The organic layer was washed sequentially with water (2×50 mL), 4% sodium carbonate (50 mL), water (50 mL), and brine (50 mL) and then concentrated under reduced pressure. The residue was purified by automated flash chromatography (silica gel eluted with a linear gradient of 0-25% CMA in chloroform, 2000 mL) followed by recrystallization from acetonitrile to provide 0.427 g of propyl 2-ethyl-1-{4-[(methylsulfonyl)amino]butyl}-1H-imidazo[4,5-c]quinolin-4-ylcarbamate as a white solid, mp 155-157° C. Anal calcd for C21H29N5O4S: C, 56.36; H, 6.53; N, 15.65. Found: C, 56.37; H, 6.37; N, 15.70.
