Project requirements III.A.I and III.A.5 can be fulfilled by simply using other aniline derivate (2-tolidine: see Figure I 4) resulting regioselectively the I ,9-phenazine derivative.

Although the selected path is long, but it is based upon reliable and simple transformations. The processes and separation techniques were suitable for scaling up . The critical chemical transformation of the selected path (I ,6 and I ,9 CHO coupling Reformatsky reaction) has many other alternative transformations in the literature available for contingency planning.
