Hydrochloric Acid → Methyl [2-[3-ethoxy-5-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzylthio]-4-methylthiazol-5-yl]acetate

Participants

Reaction Steps

A mixture of methyl (2-mercapto-4-methylthiazol-5-yl)acetate (455 mg), 4-(3-chloromethyl-5-ethoxyphenoxymethyl)-5-methyl-2-phenyloxazole (800 mg), potassium carbonate (465 mg) and N,N-dimethylformamide (20 ml) was stirred at room temperature for 2 hrs. The reaction mixture was poured into water, neutralized with 2N hydrochloric acid and extracted with ethyl acetate. The ethyl acetate layer was washed with water, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and methyl [2-[3-ethoxy-5-(5-methyl-2-phenyl-4-oxazolylmethoxy)benzylthio]-4-methylthiazol-5-yl]acetate (1.02 g, yield 87%) was obtained as an oil from a fraction eluted with ethyl acetate-hexane (1:3, volume ratio).
