Reaction Steps
This phenazine was reduced with a 3:1 potassium/sodium metal alloy in dimethoxyethane, to the brick red alkali metal adduct. Alkylation occurred over 1 hour with addition of iodomethane. Residual K/Na alloy was quenched with addition of ethanol. The product was isolated with column chromatography and was recrystallized from ethylacetate/hexane. 2.0 grams of product was isolated for a 38% overall yield.
