Versuchsvorschrift

2-[(2-Bromo-pyridin-4-ylmethyl)-amino]-6-fluoro-N-(2-methyl-2H-indazol-6-yl)-benzamide was prepared from methyl 2-amino-6-fluorobenzoate via reductive amination with 2-bromo-pyridine-4-carbaldehyde, followed by subsequent amidation with 6-amino-2-methyl-indazole in analogy to the procedures detailed in WO2004/013102, particularly Example 6A, supra; 1H-NMR (300 MHz, d6-DMSO) 10.51 (1H, s), 8.31 (1H, d), 8.26-8.28 (2H, m), 7.65 (1H, d), 7.59 (1H, s), 7.40 (1H, d), 7.13-7.25 (2H, m), 6.73 (1H, t), 6.50 (1H, t), 6.29 (1H, d), 4.47 (2H, d), 4.13 (3H, s).
