    摘要: A method for preparing a compound of formula (I), wherein R.sub.1 and R.sub.2, which are the same or different, are a hydrogen atom or an alkyl or alkoxy radical, or R.sub.1 and R.sub.2, taken together with the carbon atom to which they are attached, form a cycloalkyl radical containing 3-6 carbon atoms. The method comprises dehalogenating a derivative of formula (lI), wherein R.sub.1 and R.sub.2 have the same meanings as in formula (1) and Hal is a chlorine or bromine atom, using 1-2 mol of triethylammonium formate, in the presence of 0.002-0.1 mol of coal-borne palladium per mol of the compound of formula (II), in aceonitrile or tetrahydrofuran and at a temperature between 50.degree. C. and the boiling point of the reaction medium. ##STR1##
