23 April 2022 0 5K Report

I obtain 2,3,3-trimethylbenzoindole through Fischer indole synthesis (88% purity). I cannot find a way to purify this intermediate, and I need a min. 99% for using into the next step for dyes synthesis. Did anyone had the chance to work with this compound, did you manage to find a way to purify it ? Thank you!
