Reaction Steps
To a mixture of 4-(4-chloromethylphenoxymethyl)-5-methyl-2-phenyloxazole (4.52 g), methyl 5-hydroxy-3-pyridinecarboxylate (2.0 g), and N,N-dimethylformamide (30 mL) was added sodium hydride (60%, oil, 0.58 g) under ice-cooling, and the mixture was stirred at room temperature for 3 hrs. The reaction mixture was poured into water, and the precipitated crystals were collected by filtration. The crystals were subjected to silica gel column chromatography to give crystals (2.41 g, 0.43%) of methyl 5-[4-[(5-methyl-2-phenyl-4-oxazolyl)methoxy]benzyloxy]-3-pyridinecarboxylate from a fraction eluted with ethyl acetate-hexane (1:1, v/v). Recrystallization from ethyl acetate-hexane gave colorless prism crystals. melting point: 138-139° C.
