実験手順

1-(10,11-Dihydro-5-methyl-dibenzo[b,e][1,4]diazepin-10-yl)-2,2,2-trifluoroethanone of Step B (1.0 g) in ethanol (25 mL) was treated with 1 N sodium hydroxide (10 mL). The reaction mixture was refluxed for five hours, cooled, all volatiles removed in vacuo and the residue triturated with water. The resulting solid was filtered off, redissolved in dichloromethane and dried over anhydrous sodium sulfate. The solution was filtered through a short column of Magnesol® which was eluted with several additional volumes of dichloromethane. The total effluent was evaporated to dryness to provide the title compound as an off-white crystalline solid (0.65 g), m.p. 115–117° C.
