1,2,4-Benzenetrimethanol → HCID 58880522, compound

Participants

Reaction Steps

4 g of (3,4-bis-hydroxymethylphenyl)methanol (23.8 mmol), 40 ml of 1,2-dimethoxyethane, 2.78 g of methyl orthoformate (26.2 mmol) and 0.24 g of Montmorillonite KSF (10 mg/mmol) are introduced into a flask. The reaction medium is stirred at room temperature for 4 hours 30 minutes and then the montmorillonite is filtered off and the 1,2-dimethoxyethane is evaporated under vacuum at 30° C. The residue is chromatographed on silica gel (dichloromethane/methanol=98/2) to give 3.2 g of (7-methoxy)-(5H,9H)-6,8-dioxabenzocyclohepten-2-yl)methanol in the form of an oil.
