Reaction Steps

To a solution of 4-hydroxybenzaldehyde (1.22 g) in pyridine (5 mL) was added dimethylcarbamyl chloride (1.0 mL) and the mixture was stirred at 60° C. overnight. Thereto was added diluted HCl and ethyl acetate and stirred. The organic layer was extracted by diatomaceous earth column. The organic layer was concentrated and the resultant crude product was purified by a column chromatography on silica gel (solvent; hexane/ethyl acetate=80:20→60:40) to give 4-formylphenyl dimethylcarbamate (1.67 g, yield: 86%).
