To a mixture of 1.00 g of 3-hydroxybenzaldehyde, 25 ml of tetrahydrofuran, 2.40 g of triphenylphosphine and 0.78 ml of 2-methylthioethanol was added dropwise 3.50 ml of diethyl azodicarboxylate (40% toluene solution), and the mixture was stirred at room temperature for 15.5 hours. The reaction solution was concentrated under reduced pressure, and the resulting residue was subjected to silica gel column chromatography to obtain 0.71 g of oily 3-(2-methylthioethoxy)benzaldehyde [Compound No. (f)].
