A Convenient and Efficient Process to 5-(2-Di-n-Propylaminoethyl)-6-hydroxyindole
摘要:
An intermolecular trapping of the Pummerer intermediate, generated from 9 with TFAA, by 4 at position 5 under mild Lewis acid conditions gave 5. Sequential treatment of S with Ra-Ni, LiAlH4 and again Ra-Ni, afforded 8 in high overall yield.
