Hydrochloric Acid → HCID 86759242, compound

Participants

Reaction Steps

A solution of 3-methoxyaniline (1.55 ml, 13.79 mol) and ethyl ∀-formylphenylacetate (2.92 g, 1.1 eq) in toluene (20 ml) is refluxed for 18 hours. After cooling, the reaction mixture is diluted with toluene (15 ml) and then acidified with 10% HCl. After extraction, the organic phase obtained is dried over MgSO4 and then evaporated under reduced pressure. The residue is purified by chromatography on a column of silica (eluent: CH2Cl2) to give 2.30 g (56%) of compound 8 (Z isomer) in the form of a yellow solid which crystallizes from methanol.
