I'm looking to know if anyone has any experience/advice.
I've protected 7-azaindole with a benzenesulfonyl protecting group and now I want to acylate at the C-3 position.
A paper I have recommends uding 5 eq. of Aluminium Trichloride and 5 eq. of the acylating agent (oxalyl chloride in this case).
I can't find any information online on whether aluminium trichloride will affect the benzenesulfonyl group in any way so I'm wondering does anyone here have any idea?
