Versuchsvorschrift

A1.12 tert-Butyl-6-amino-7-iodo-1-methyl-1H-imidazo[4,5-c]pyridin-4-yl(methyl)carbamate (3.2 g, 7.9 mmol), dichlorobis(triphenylphosphine)palladium (270 mg, 0.38 mmol), 3-ethynyl-5-fluorobenzonitrile (C1.2) (1.5 g, 10 mmol), CuI (75 mg, 0.39 mmol), diisopropylamine (15 mL) were added to N,N-dimethylformamide (15 mL). The reaction mixture was heated at 90° C. (in preheated oil bath) for 60 min. Additional 3-ethynyl-5-fluorobenzonitrile (C1.2) (0.5 g, 3.4 mmol) was added to the reaction mixture and heated for another 60 min. The reaction was cooled and diluted with ethyl acetate and washed several times with water. The solvent removed under reduced pressure and the residue was purified by silica gel column chromatography (50%-70% ethyl acetate/hexane) to give 3.0 g (90%) of C1.3. LCMS B: Ret time 2.98 min, (M+H)+=421.31, 1H NMR, 400 MHz, CDCl3: 7.62 (s, 1H), 7.57 (s, 1H), 7.42 (dm, 1H), 7.35 (dm, 1H), 5.00 (bs, 2H), 4.05 (s, 3H), 3.39 (s, 3H), 1.44 (s, 9H).
