Procedure

A suspension of NaH (0.84 g, 20.8 mmol) was added at room temperature to a solution of ethyl 4-methylthiophenylacetate (1.1 g, 5.2 mmol) in ethyl formate (20 mL). The mixture was stirred at room temperature for 1 hour and then cold 0.5 N HCl (20 mL) was added slowly. The crude reaction was then extracted with ether, and the organic layer was washed with sodium bicarbonate, brine, dried over magnesium sulfate, filtered, and concentrated to yield 1.2 g of ethyl 4-methylthio-α-formyl-phenylacetate as a colorless oil, which was used in the next step without purification.
