Versuchsvorschrift

To a solution of 1-[3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-4-hydroxy-phenyl]-3-(2,4-difluoro-phenyl)urea (see above) (0.035 g, 0.09 mmol) in THF (3 mL), triphenyl phosphine (0.071 g, 0.27 mmol) and 3-dimethylamino propanol (31.6 μL, 0.27 mmol) were added followed by dropwise addition of diisopropyl azodicarboxylate (DIAD) (52.3 μL, 0.27 mmol). The reaction mixture was stirred at room temperature for 2 hours, concentrated to give a crude product that was purified via preparative HPLC. The corresponding fractions were collected, neutralized with 1N NaOH and extracted with EtOAc four times. A second purification by flash chromatography (SiO2, CH2Cl2/MeOH gradient elution) afforded Compound 133 as an off-white solid in 25.4% yield. LCMS m/z (%)=464 (M+H 35Cl, 100), 466 (M+H 37Cl, 39). 1H NMR (400 MHz, DMSO-d6) δ: 9.02 (s, 1H), 8.47 (s, 1H), 8.07-8.01 (m, 1H), 7.62 (s, 1H), 7.51 (d, J=8.90 Hz, 1H), 7.38 (s, 1H), 7.33-7.28 (m, 1H), 7.15 (d, J=9.02 Hz, 1H), 7.03-6.97 (m, 1H), 4.11-3.94 (m, 2H), 3.63 (s, 3H), 2.28-2.18 (m, 2H), 2.11 (s, 6H), 1.78-1.69 (m, 2H).
