Procedure
Sodium hydride (0.008 g, 60% in oil) was added to a solution of 5,11-dihydro-11-ethyl-5-methyl-2-(3-pyrrolyl)-6H-dipyrido[3,2-b:2',3'-e][1,4]diazepin-6-one (0.065 g) in dry DMF (3 mL) and stirred for 30 min. Methyl iodide (0.2 mL) was added and the reaction mixture was stirred for an additional 2 h. Water was added and the product was extracted with CH2Cl2, dried (anhyd Na2SO4), filtered, and evaporated. The residue was chromatographed over silica gel (ethyl acetate/hexanes, 1:1) and was further purified by preparative plate chromatography (ethyl acetate/hexanes, 1:1) to give 0.040 g of the title compound, mp 187°-188° C.
