Trimethyl orthoformate → 1-(Dimethoxymethyl)-4-(methylsulfanyl)benzene

Participants

Reaction Steps

A suspension of K-10 (32 g) in trimethyl orthoformate (115 ml, 1.05 mol) was added to a solution of 4-(methylthio)benzaldehyde (31.0 g, 0.203 mol) in dichloromethane (300 ml) at 0° C. The obtained mixture was stirred at room temperature for 20 minutes and filtered to remove the K-10. The filter cake was washed with dichloromethane. The filtrate and washings were together washed with a saturated aqueous solution of sodium hydrogencarbonate and a saturated aqueous solution of common salt, dried over magnesium sulfate and concentrated in a vacuum to give the title compound as a pale-yellow oil (39.0 g, 96%).
