Reaction Steps
A mixture of methyl (3-hydroxy-1-methyl-1H-pyrazol-4-yl)acetate (255 mg), 5-chloromethyl-2-(2-phenyl-4-thiazolylmethoxy)pyridine (475 mg), potassium carbonate (415 mg) and N,N-dimethylformamide (10 ml) was stirred at 60° C. for 5 hrs. The reaction mixture was poured into water and the mixture was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine, dried (MgSO4) and concentrated. The residue was subjected to silica gel column chromatography, and methyl [1-methyl-3-[6-(2-phenyl-4-thiazolylmethoxy)-3-pyridylmethoxy]-1H-pyrazol-4-yl]acetate (581 mg, yield 86%) was obtained as colorless crystals from a fraction eluted with ethyl acetate-hexane (2:1, volume ratio). The crystals were recrystallized from ethyl acetate-hexane. melting point: 85–86° C.
