Procedure

Nine grams (0.033 mol) of 5-chlorocarbonyl-5,10-dihydro-11H-dibenzo[b,e][1,4]diazepin-11-one, 5.3 gm (0.05 mol) of sodium carbonate, and 5.2 gm (0.036 mol) of 1-methyl-4-methylamino-piperidine were refluxed in 150 ml of acetonitrile for 15 minutes under stirring. The mixture was filtered while hot, and then the filtrate was placed on a silica gel column and eluted first with acetonitrile and then with a methylene chloride/ethyl acetate/cyclohexane/methanol/ammonia (175:75:23:23:3) mixture. The desired fraction was concentrated by evaporation in vacuo, and the residue was recrystallized from acetonitrile.
