Abstract
The invention concerns a 2-ethyl-3-hydroxy-2,3-dihydrobenzofuran of general formula (F) wherein: R represents a hydrogen atom, a halogen, a lower alkyl, lower alkoxy or hydroxy radical; and Z represents a C1-C3 alkoxy group or an amino group, and its use for preparing an Efaroxan derivative. The invention also concerns the method for preparing the derivative of general formula (F) from a corresponding salicylic aldehyde derivative.
