Versuchsvorschrift

To a solution of {5-tert-butyl-2-[3-(3-hydroxy-propoxy)-phenyl]-2H-pyrazol-3-yl}-carbamic acid phenyl ester (200 mg, 0.49 mmol) in THF was added 4-(pyridin-4-yloxy)-phenylamine (109 mg, 0.59 mmol). The reaction mixture was heated at 60° C. for 16 h. The reaction mixture was cooled to room temperature, concentrated at reduced pressure, and the residue was dissolved in DMF and methanol. The product was isolated by preparative HPLC, and the HPLC fraction containing the desired product was concentrated at reduced pressure and then partitioned between EtOAc (20 mL) and saturated aq Na2CO3 (10 mL). The organic layer was dried over Na2SO4 and evaporated to give 1-{5-tert-butyl-2-[3-(3-hydroxy-propoxy)-phenyl]-2H-pyrazol-3-yl}-3-[4-(pyridin-4-yloxy)-phenyl]-urea (51.3 mg, 21%). 1H-NMR (DMSO-d6) δ 7.50 (d, 2H), 7.10 (m, 5H), 6.90 (d, 2H), 6.70 (m, 3H), 6.40 (s, 1H), 4.0 (t, 2H), 3.60 (t, 3H), 1.80 (m, 2H), 1.30 (s, 9H); MS LC-MS [M+H]+=502.1, RT=2.36 min.
