Trifluoroacetic acid → HCID 22416596, compound

Participants

Reaction Steps

A 10 ml portion of trifluoroacetic acid was added to 220 mg of the product of Example 23, and the mixture was stirred for 4 hours at room temperature. The reaction mixture was diluted with ethyl acetate (100 ml), washed with water, saturated sodium bicarbonate aqueous solution, water and saturated sodium chloride aqueous solution in that order and then dried over anhydrous sodium sulfate. After distilling off the solvent, the resulting residue was purified by subjecting it to silica gel column chromatography (toluene-ethyl acetate, 1:1) to obtain 1,4-bis[[4-[(2,4-dioxo-5-oxazolidinyl)methyl]phenoxy]methyl]benzene.
