DIBENZO(FH)QUINOXALINE Use and Manufacturing

Under nitrogen 18.6g (0.31 mmol) of 1, 2-diaminoethane was added 1000ml of toluene 55.0g (0.26 mol) of 9, 10-dioxo Philippines.Use trap the red suspension is heated under reflux for 24 hours (separation of water: approximately 1ml).The resulting brownish suspension is treated with 50.0g of manganese oxide (IV), and heating continued under reflux until no intermediate product is visible on TLC.The hot black suspension was filtered by washing with 200ml of toluene and the solid residue.The solution was concentrated and the resulting solid was further dried in vacuo to give a pale yellow solid as the title compound (Yield: 58.0g (97percent)).
