Reaction Steps

In methanol (5 mL) was dissolved 5-(diethoxymethyl)picolinaldehyde (148 mg, 0.707 mmol) obtained in Step 1. To the solution were added toluene-4-sulfonylmethylisocyanide (345 mg, 1.77 mmol) and potassium carbonate (244 mg, 1.77 mmol) and the mixture was stirred at room temperature for 8 hours. Water was added to the reaction mixture. Extraction with ethyl acetate, washing with saturated brine and drying over anhydrous sodium sulfate were performed. After filtration, the solvent in the filtrate was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=7/3) to give 5-(5-(diethoxymethyl)pyridin-2-yl)oxazole (161 mg, 92% yield).
