Ce procéd 6 connu de condensation des produits de formule (II) et (III) a divers inconvénients, notamment des rendements médiocres On pense que c'est généralement la présence d'accepteur d'acide qui abaisse le rendement par le fait qu'il favorise la réaction de diacylation De plus l'utilisation d'un accepteur d'acide rend l'isolement et la purification des produits firaux plus difficiles et plus coûteux.  This known method of condensation of the products of formulas (II) and (III) has various drawbacks, in particular poor yields.
