A compound (I) is prepared by reacting at least one (meth) acrylate (II) with a heterocyclic alcohol (III), in the presence of a catalyst consisting of a mixture formed (a) of at least one alcoholate of magnesium and (b) of a component chosen from calcium chelates with 1,3-dicarbonyl compounds, tin dialkyloxides, tin dialkylalkoxides and tin dialkyldiesters. R = C₁-C₄ alkyl. R¹ = H, CH₃; A, B = straight or branched C₂-C₅ hydrocarbon chain; R = C₁-C₄ alkyl. |
