실험 절차

The mixture of benzo[a]phenazine-11-carboxylic acid (II.20) and benzo[a]phenazine-8-carboxylic acid (885 mg), prepared as described in Reference Example 1L above, was heated to reflux in a mixture of methanol (40 mL) and acetyl chloride (920 μL) for 90 minutes. The reaction mixture was then cooled slowly to yield the title compound as a single isomer which was collected by filtration (377 mg).
