Reaction Conditions

Reaction Steps

The resulting compound 5.0 g (0.02 mmol) was mixed with polyphosphoric acid 176 g and heated at 120° C. for 2 hours. After heating, the reaction mixture was poured into ice water. The resulting solution was neutralized with an aqueous solution saturated with potassium hydrogencarbonate and deposited crystals were collected by filtration to obtain a mixture of 1-methyl-6,11-dihydroindolo[3,2-b]-quinoline-6-one and 3-methyl-6,11-dihydroindolo[3,2-b]-quinoline-6-one (4.1 g (yield: 83%)).
