Procedure

Compound (157a) (0.080 g) was dissolved in DMSO (1.2 mL), and potassium carbonate (0.160 g), copper(II) oxide (nanopowder) (0.009 g), and 4-(pyridin-3-yl)-1H-imidazole hydrochloride (0.053 g) were added to the resulting solution, followed by stirring at 120° C. for 4 hr. The reaction solution was diluted with ethyl acetate, and insoluble matters were filtered by celite. The solvent was distilled away, and the residue was purified by neutral silica gel column chromatography (chloroform/methanol) to obtain compound (176) (0.031 g, 30%).
