실험 절차
Under a nitrogen atmosphere, trimethyl orthovalerate (2.7 mL, 16 mmol) was added dropwise to a solution of 7-benzyloxy-N4-(2-phenoxyethyl)quinoline-3,4-diamine (3.0 g, 7.8 mmol), prepared as described in Parts A and B of Example 46, in xylenes (30 mL), and the reaction was heated at reflux for 24 hours. The reaction mixture was allowed to cool to ambient temperature; a precipitate formed, which was isolated by filtration, washed with hexanes, and dried for two hours in a vacuum oven to provide 2.96 g of 7-benzyloxy-2-butyl-1-(2-phenoxyethyl)-1H-imidazo[4,5-c]quinoline.
