Stage #1: With tert.-butyl lithium In tetrahydrofuran; pentane at -70℃; for 0.25 h; dry ice bath
Stage #2: at -70 - 20℃; for 0.5 h;
Stage #3: With water; ammonium chloride In tetrahydrofuran; pentane at 20℃;
EXAMPLE 49 3-Trifluoromethoxy-10-methyl-9H-imidazo[1,5-a][1,2,4]triazolo[1,5-d][1,4]benzodiazepine; a) 2-Fluoro-5-trifluoromethoxy-benzaldehyde; A solution of 1-fluoro-4-trifluoromethoxy-benzene (21.0 g, 117 mmol) in THF (233 ml) was cooled to <-70° C. Tert.-butyllithium (86 ml of a 1.5 molar solution in pentane, 129 mmol) was added at such a rate that temperature was kept <-70° C. Stirring in the dry ice bath was continued for 15 min, then DMF (11.6 ml, 150 mmol) was added dropwise keeping temperature <-70° C. After 30 min the reaction mixture was allowed to reach rt, quenched with saturated NH4Cl solution and extracted with ether. The organic phase was washed with brine, concentrated and chromatographed (SiO2, heptane:ethyl acetate=100:0 to 80:2). The title compound (11.0 g, 53percent) was obtained as a light yellow oil. 1H-NMR (300 MHz, DMSO): δ=7.60 (t, J=9.2 Hz, 1H), 7.75-7.85 (m, 2H), 10.20 (s, 1H).
