Wang Jinrong

maybe you can try non-alcohol solvent or an aqueous mixed solvent. Nothing happens maybe due to NaOH poorly souble in alcohol solvent.

Lucas Lima Zanin

Wang Jinrong I'll try, thank you.

Jordi Agramunt

I would either try KOH or adding catalytic amounts of DMAP (dimethyl amino pyridine)

Jordi Agramunt Thank you for the idea!
