反応手順

A reaction was conducted by a similar procedure to that described in Example 52 using triethylamine (0.32 ml), 2-naphthoyl chloride (153 mg), 5-[4-[6-(4-aminophenoxy)-1-methyl-1H-benzimidazol-2-ylmethoxy]benzyl]thiazolidine-2,4-dione dihydrochloride (400 mg) and anhydrous N,N-dimethylformamide (8 ml). The reaction mixture was concentrated under reduced pressure. To the residue was added ethyl acetate and water. The precipitate was isolated by filtration to afford the title compound (337 mg, white powder, mp 221-223° C.).
