Triethylamine → HCID 18537603, compound

Participants

Reaction Steps

A reaction was conducted by a similar procedure to that described in Example 52 using triethylamine (0.32 ml), 3-chlorobenzoyl chloride (0.09 ml), 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. The residue was partitioned between ethyl acetate and water. The extract was washed with saturated aqueous sodium chloride solution, dried over anhydrous sodium sulfate and then concentrated. The residue was chromatographed on a silica gel column using ethyl acetate:n-hexane=3:2→5:2 as the eluant to afford the title compound (232 mg, white powder, mp 238-239° C.).
