実験手順
A solution of the ketal of Step A, above, (10 g, 0.06 mol), 2-chloromethylquinoline (10.6 g, 0.06 mol), cesium carbonate (20.0 g, 0.06 mol) and potassium iodide (0.16 g, 0.001 mol) in 250 ml acetone is refluxed 20 hours. The solution is filtered through Celite and silica gel and the solvent is removed in vacuo. The resulting crude solid is recrystallized using 2-propanol to give 13.7 g of crystalline solid (74% yield) m.p. 67°-69° C.
