    摘要: The present invention relates to a process for the preparation of a compound of formula (I) said process comprising the steps of : a) reacting a compound of formula (II), with an acylating or a silylating agent to produce a compound of formula (III), wherein P
    1 and P
    2 are each independently a protecting group selected from R
    2- Si-R
    3 R
    4 , or R
    1 CO-, wherein R
    1 is a group selected from C
    1-6 alkyl or C
    3-6 cycloalkyl, each group being optionally substituted by one or more substituents independently selected from fluoro or C
    1-4 alkyl; R
    2 , R
    3 and R
    4 are each independently a group selected from C
    1-6 alkyl or phenyl, each group being optionally substituted by one or more substituents independently selected from fluoro or C
    1-4 alkyl; b) reacting the compound of formula (III) in the presence of palladium acetate or a derivative thereof to produce compound of formula (IV); and c) reacting the compound of formula (IV) with a reducing agent to produce compound of formula (I).
