Versuchsvorschrift

To a solution of 4-bromo-1,3-dimethyl-1H-pyrazole-5-carboxylic acid (20.0 mg, 0.0913 mmol) in THF (3 mL, 30 mmol) was added 1.0 M of BH3.THF in THF (0.456 mL, 0.456 mmol), and the mixture was heated to 60° C. overnight. The material was extracted with EtOAc, and washed with sat. NaHCO3 (3×). The organic layer was concentrated in vacuo. 3-[(S)-1-(2-Chloro-3-fluoro-6-methoxyphenyl)-ethyl]-5-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (15.0 mg, 0.0348 mmol), (1,1′bis-(diphenylphosphino)-ferrocene) palladium dichloride (3.34 mg, 0.00456 mmol), K2CO3 (18.9 mg, 0.137 mmol) and 4:1 dioxane:H2O (1 mL, 10 mmol) were added, and the mixture was heated to 95° C. for 30 min. The solution was used directly for HPLC purification, and the fractions containing the pure product were concentrated in vacuo to afford the title compound as a white solid. 1H NMR (400 MHz, CD3OD): δ=1.80 (d, J=7.1 Hz, 3H), 2.04 (s, 3H), 3.64 (br. s., 3H), 3.89 (s, 3H), 4.46 (s, 2H), 5.05-5.15 (m, 1H), 6.88 (dd, J=9.1, 4.3 Hz, 1H), 7.07 (t, J=8.8 Hz, 1H), 7.36 (s, 1H), 7.38 (br. s., 1H), 8.07 (d, J=2.0 Hz, 1H). MS (ES+): m/z=429.14/431.15 (100/50) [MH+]. HPLC: tR=1.38 min (polar—3 min, UPLC-ACQUITY).
