Dimethylformamide → HCID 11123751, compound

Participants

Reaction Steps

A mixture of 4-(chloromethyl)-2-phenylthiazole (368 mg), methyl E-4-(4-hydroxybenzyloxyimino)-4-phenylbutyrate (500 mg), potassium carbonate (442 mg) and N,N-dimethylformamide (10 ml) was stirred at room temperature for 18 hours. Water was added to the reaction mixture and extracted with ethyl acetate. The ethyl acetate layer was washed with an aqueous saturated solution of sodium chloride, dried (MgSO4) and concentrated. The residue was subjected to silica gel chromatography to obtain methyl E-4-phenyl-4-[4-(2-phenyl-4-thiazolylmethoxy)benzyloxyimino]butyrate (494 mg, yield 63%) as a colorless oil from an ethyl acetate-hexane (2:9, v/v)-eluted fraction.
