실험 절차

To a stirred solution of [2-methoxy-4-(3-methyl-pyrazol-1-yl)-phenyl](5H,11H-pyrrolo[2,1-c][1,4]benzodiazepin-10-yl) methanone from Example 107 (0.57 g) in warm methanol (10 ml) was added N,N,N,N′-tetramethyldiaminomethane (0.392 ml) and acetic acid (0.164 ml). Following the addition of aqueous 37% formalin solution (2.9 ml) the reaction was stirred for fifteen minutes. The mixture was concentrated in vacuo and partitioned between dichloromethane and sodium hydrogen carbonate. The organic phase was removed, washed with brine and dried over anhydrous magnesium sulfate. The solution was filtered and the solvent removed in vacuo. The residue was purified by flash column chromatography on silica eluting with chloroform/methanol (50/1) to afford a solid. Recrystallisation of the solid from acetone gave the title compound as a colorless solid, m.p. 196-198° C.
