Procedure

Potassium carbonate (9.07 g) and methyl iodide (3.92 ml) were added to a solution of the compound of Example B220 (13.30 g) in acetone (75 ml), and this reaction mixture was stirred while heating under reflux for 4 hours. The reaction mixture was filtered through celite, ether was added to remove insoluble material by filtration, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to give the title compound (9.52 g).
