Versuchsvorschrift
The above compound, N-ethoxycarbonyl-2-amino-2′ methyl biphenyl (6.7 g, 26 mmol) was added to polyphosphoric acid (15 g) and heated to 170° C. overnight. After cooling, water was added and the white precipitate collected by vacuum filtration to give the 10-methyl-phenanthridinone (3.5 g, 65% yield) whose structure was consistent with CGMS and NMR.
