What will be procedure for diazotization linkage at 2nd position of 3- substituted indole?

06 June 2016 1 9K Report

I want to couple 3-substitued indole via 2nd position with aryl diazonium salts.

I have tried many procedures but not able to get compound of desired purity.

So what will be the exact procedure for this coupling?

you can use cation exchange resin immobilized diazonium ion and carry out the coupling reaction with 3-sub indole in organic solvent.
