Vorschrift

1-(2-Aminoethyl)-2-butyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-4-amine (2.00 g, 5.50 mmol) was treated with triethylamine (1.01 mL, 7.26 mmol) and isobutyryl chloride (0.64 mL, 6.10 mmol) according to the method described in Part B of Examples 372–376. The crude product was recrystallized from isopropanol (4 mL/g) and then triturated with acetonitrile (12.5 mL/g), isolated by filtration, and dried overnight in a drying oven to provide 0.61 g of N-{2-[4-amino-2-butyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-1-yl]ethyl}-2-methylpropanamide as a white solid, mp 228–230° C.
