实验过程

The methods described in Parts A of Example 204 were used to treat 1-[3-(3-amino-7-phenylquinolin-4-ylamino)propyl]pyrrolidin-2-one (1.19 g, 3.30 mmol) with 3-methoxypropionyl chloride (0.45 mL, 4.1 mmol) to afford 1-{3-[2-(2-methoxyethyl)-7-phenyl-1H-imidazo[4,5-c]quinolin-1-yl]propyl}pyrrolidin-2-one, which was oxidized and then aminated according to the methods described in Parts H and I of Example 1. The product from amination was recrystallized twice from acetonitrile and dried in a vacuum oven at 60° C. to provide 1-{3-[4-amino-2-(2-methoxyethyl)-7-phenyl-1H-imidazo[4,5-c]quinolin-1-yl]propyl}pyrrolidin-2-one as a light brown solid, mp 187–191° C.
