    摘要: This invention is concerned with a novel process for the preparation of a compound of structural formula (I) wherein R?1 and R2¿ independently are aryl, C¿2-15? alkenyl or C1-15 alkyl, either unsubstituted or substituted with one or three substituents, which can be the same or different, selected from the group consisting of Ra, wherein Ra belongs to a group consisting of C1-6 alkyl, aryl, halo, -N(R?3)¿2, -NO2, -CN, -OR3, -C¿3-6? cycloalkoxy, -CO(R?3¿), -COOR3, SO2R3 and -SR3; wherein R3 is selected from the group consisting of hydrogen, C¿1-6? alkyl, C2-6 alkenyl and aryl, said alkyl, alkenyl or aryl optionally substituted with 1 to 3 groups of R?a¿, which is an important antiasthmatic agent.
