Isopropyl isocyanate → N-{2-[4-amino-2-butyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-1-yl]ethyl}-N'-(1-methylethyl)urea

참여 물질

반응 단계

Isopropyl isocyanate (0.29 mL, 3.1 mmol) was added slowly to a suspension of 1-(2-aminoethyl)-2-butyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-4-amine (1.13 g, 3.1 mmol) in chloroform (113 mL). A precipitate formed within 15 minutes, was isolated by filtration, and was dried overnight in an oven to provide 0.66 g of N-{2-[4-amino-2-butyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-1-yl]ethyl}-N′-(1-methylethyl)urea as a white solid, mp 240–241° C.
