Versuchsvorschrift

To a solution of 1,1′-carbonyldiimidazole (62 mg, 0.38 mmol) in benzene (2 mL) and CH2Cl2 (1 mL) was added 4-(4-amino-3-fluorophenoxy)-N-methylpyridine-2-carboxamide (100 mg, 0.38 mmol). The resulting solution was stirred at room temperature for 16 h, then was treated with 1-methyl-5-aminoindazole (56 mg, 0.38 mmol). The reaction continued to stir at room temperature for 18 h. The mixture was concentrated under reduced pressure and the residue was triturated with Et2O. The solid was collected by filtration, and then purified by preparative HPLC to afford 44 mg (27%) of the title product. 1H-NMR (DMSO-d6) δ 2.78 (d, J=4.8, 3H), 4.01 (s, 3H), 7.02-7.07 (m, 1H), 7.14-7.18 (m, 1H), 7.28-7.36 (m, 2H), 7.39 (d, J=2.9, 1H), 7.52-7.59 (m, 1H), 7.89-7.96 (m, 2H), 8.23 (t, J=9.0, 1H), 8.49 (d, J=4.9, 1H), 8.57-8.63 (m, 1H), 8.71-8.81 (m, 1H), 9.06 (s, 1H); MS LC-MS [M+H]+=435.1; mp 231-234° C.
