Reaction Steps

A thick walled glass tube, equipped with stir bar, was charged with palladium (II) acetate (67 mg, 0.3 mmol), acetonitrile (15 mL), N-allyl-2-pyrrolidone (650 mg, 5.17 mmol), triethylamine (2.1 ml, 15.65 mmol), tri-o-tolylphosphine (275 mg, 0.9 mmol) and 8-bromo-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-4-amine (U.S. Patent Application Publication No. US 2004/0147543 Example 11, 1.5 g, 4.7 mmol). The reaction mixture was purged with nitrogen, sealed and heated at 120° C. for 24 hours. The reaction mixture was concentrated to dryness. The reaction mixture was slurried in a mixture of 1% aqueous sodium carbonate (75 mL) and chloroform (100 mL). The layers were separated. The aqueous layer was extracted with chloroform (2×25 mL). The combined organic fractions were concentrated to dryness and purified by chromatography using a HORIZON HPFC system (silica cartridge, eluting with 0-8% methanol/dichloromethane) to provide 1-{(2E)-3-[4-amino-1-(2-methylpropyl)-1H-imidazo[4,5-c]quinolin-8-yl]prop-2-enyl}pyrrolidin-2-one.
