1-[3-(3-Amino-7-phenylquinolin-4-ylamino)propyl]pyrrolidin-2-one (2.21 g, 6.13 mmol) was treated with ethoxyacetyl chloride (0.95 mL, 8.76 mmol) according to the methods described in Parts C and D of Examples 152–156. Triethylamine (8.6 mmol) was added in Part C. The product from Part D was purified by column chromatography on silica gel (eluting with acetone and then chloroform:methanol in a gradient from 95:5 to 90:10) to provide 1.49 g of 1-[3-(2-ethoxymethyl-7-phenyl-1H-imidazo[4,5-c]quinolin-1-yl)propyl]pyrrolidin-2-one as a brown solid.
