Versuchsvorschrift

Pd2(dba)3 (9.2 mg, 0.01 mmol) was added to a mixture of tert-butyl 4-(6-chloro-1-(methylsulfonyl)-1H-pyrrolo[3,2-c]pyridin-2-yl)-1H-pyrazole-1-carboxylate (15) (40 mg, 0.101 mmol), cesium carbonate (131 mg, 0.403 mmol), 4-fluoroaniline (19 μL, 0.202 mmol) and di-tBuX-Phos (17.1 mg, 0.040 mmol) in t-BuOH containing water (3%) (1.1 mL). The reaction mixture was heated at 80° C. for 1.5 hr under microwave irradiation. It was then diluted with EtOAc and washed with water. The organic extracts were dried over MgSO4, filtered and concentrated under vacuum. The residue was then purified by prep TLC (DCM/MeOH, 95/5) to afford 20 mg of title compound mixed with some starting material. This mixture was used in the next step without further purification. 1H NMR (500 MHz, CDCl3) 1.69 (s, 9H), 2.90 (s, 3H), 6.69 (d, J=0.9 Hz, 1H), 7.05-7.09 (m, 2H), 7.33-7.37 (m, 2H), 7.46 (br m, 1H), 7.93 (d, J=0.9 Hz, 1H), 8.35 (d, J=0.9 Hz, 1H), 8.48 (m, 1H).
