Versuchsvorschrift

To a solution of 2-[5-(2-aminomethyl-4-fluoro-phenoxy)-indazol-1-yl]-N,N-dimethylacetamide (46d) (0.010 g, 0.029 mmol) and (5-tert-butyl-2-p-tolyl-2H-pyrazol-3-yl)-carbamic acid 2,2,2-trichloroethyl ester (0.013 g, 0.032 mmol) in DMF (1 mL) was added DIEA (0.01 mL, 0.058 mmol). The mixture was heated to 80° C. for 18 hours under N2 atmosphere. The mixture was concentrated under reduced pressure and dissolved in dichloromethane. The solution was washed with 1N HCl, filtered, and concentrated under reduced pressure. The oil was chromatographed eluting with dichloromethane/ether (10:1) and then 5% MeOH in dichloromethane to afford 6.3 mg of pale yellow oil (36% yield). MS (APCI+) m/z 598 (M+1) detected; 1H NMR (400 mHz, DMSO-D6) δ 8.29 (s, 1H), 7.97 (s, 1H), 7.58 (d, 1H), 7.36 (d, 2H), 7.28 (d, 2H), 7.19 (d, 1H), 7.12 (d, 1H), 7.07 (m, 2H), 6.99 (m, 1H), 6.84 (m, 1H), 6.24 (s, 1H), 5.40 (s, 2H), 4.28 (d, 2H), 3.10 (s, 3H), 2.84 (s, 3H), 2.35 (s, 3H), 1.25 (s, 9H).
