Versuchsvorschrift

1-(2-Aminoethyl)-2-ethoxymethyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-4-amine (2.00 g, 5.50 mmol) was treated with triethylamine (1.00 mL, 7.20 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 93:7 acetonitrile:water and then from isopropanol (7.3 mL/g) and dried for two hours in a drying oven to provide 0.78 g of N-{2-[4-amino-2-ethoxymethyl-7-(pyridin-3-yl)-1H-imidazo[4,5-c]quinolin-1-yl]ethyl}-2-methylpropanamide as a white solid, mp 213-215° C.
