Versuchsvorschrift

A mixture of 1-(4-(6-(2-amino-5-bromonicotinoyl)pyridin-2-yl)-1,4-diazepan-1-yl)-3,3,3-trifluoropropan-1-one (355 mg, 0.73 mmol), vinyl boronic acid pinacol ester (0.15 ml, 0.88 mmol), tetrakis(triphenylphosphine)palladium(0) (42 mg) and a 2M aqueous solution of sodium carbonate (2 ml) in ethanol (1 ml) and toluene (3 ml) was heated under microwave irradiation at 110° C. for 5 hours. The reaction mixture was concentrated in vacuo. The residue was slurried in ethyl acetate, filtered to remove the inorganic salts and concentrated to dryness in vacuo. The residue was purified by reverse phase preparative HPLC [Waters Sunfire C18, 10 μM, 100 Å column, gradient 10%-95% B (solvent A: 0.05% TFA in water; solvent B: CH3CN) over 16 minutes at 25 mL/min]. The fractions were collected, passed through a sodium bicarbonate cartridge and freeze-dried to give the title compound as an orange solid (68 mg, 21% yield).
