실험 절차

To 4.1 g (0.012 mol) of 8-mercapto-[1,3]dioxolo-[4,5-g]quinoline-7-carboxylic acid (2-pyridin-2-yl-ethyl)-amide (from Preparation 34) and 5 mL (0.035 mol) of triethylamine in 750 mL of methanol was added 2.95 g (0.012 mol) of iodine in 100 mL of methanol. The mixture was heated at reflux for 2 hours, cooled, and then concentrated to an oil. The residue was slurried in water, and the solid was collected and recrystallized in ethanol to give 3.5 g of the title compound, mp 200°-201° C.
