Versuchsvorschrift
To a solution of 1,1-dimethylethyl [5-({[(4S)-6-(4-chlorophenyl)-1-methyl-8-(methyloxy)-4H-[1,2,4]triazolo[4,3-a][1,4]benzodiazepin-4-yl]acetyl}amino)pentyl]carbamate (for a preparation see Reference compound H) (0.2 g, 0.34 mmol) in dichloromethane (3 ml) was added trifluoroacetic acid (0.053 ml, 0.68 mmol) dropwise at 0° C. The reaction mixture was stirred for 3 h from 0° C. to room temperature. The reaction mixture was concentrated to dryness to afford the title compound as a hygroscopic yellow oil (200 mg)
