Abstract
Process for the production of derivatives of estradiol, of formula Ia, **(See formula)** where R1 means an alkyl group containing from 1 to 3 carbon atoms, R5 means an alkyl group containing from 1 to 4 carbon atoms, R'2a means an alkyl group containing from 1 to 4 carbon atoms, a cyclopentyl group or a cyclohexyl group, characterized in that it comprises esterifying a compound of formula III, **(See formula)** wherein R1 and R'2a have the meanings indicated above, with a reactive functional derivative of a compound of formula IV, R5OH IV wherein R5 has the meaning indicated above, the derivative of the compound of formula IV being preferably a diazoalkane and the esterification preferably being carried out at a temperature of 15 to 25ºC.
