Методика

To a stirred solution of 1.5 mmol of 2-methylbenzoyl chloride in 10 ml of methylene chloride is added 3 mmol of triethylamine. After stirring for 15 minutes, 1.5 mmol of 4,5-dihydro-5-(4-aminobenzoyl)pyrrolo[1,2-a]quinoxaline is added and the mixture stirred for 5 hours. The reaction mixture is washed with water, 1N HCl, NaHCO3, and brine. The reaction mixture is dried with Na2 SO4, filtered and evaporated in vacuo to give a solid which is purified by flash chromatography to give the desired product as a solid, m.p. 206°-207° C.
