実験手順

2-(2-{4-Amino-2-(2-methoxyethyl)-1-[3-(2-oxopyrrolidin-1-yl)propyl]-1H-imidazo[4,5-c]quinolin-8-yl}ethyl)-1H-isoindole-1,3(2H)dione (2.2 g, 4.1 mmol) was dissolved in 2:1 ethanol:tetrahydrofuran (40 mL), combined with hydrazine hydrate (410 mg, 8.2 mmol) and heated at reflux temperature for three hours. Additional hydrazine hydrate (0.25 mL) was added and the solution was refluxed for an additional 1.5 hours. The reaction was cooled to ambient temperature, filtered and the filtrate concentrated under reduce pressure. Purification by chromatography using a HORIZON HPFC system (silica cartridge, eluting with a 0-40% CMA:chloroform gradient over 3.8 L) provided 650 mg of 1-{3-[4-amino-8-(2-aminoethyl)-2-(2-methoxyethyl)-1H-imidazo[4,5-c]quinolin-1-yl]propyl}pyrrolidin-2-one as an off-white solid. MS (ESI) m/z 411 (M+H)+.
