Reaction Steps

3-(3-Styryl-4,5-dihydro-1H-indazol-6-yloxy)-phenylamine was converted to 5-methyl-thiazole-2-carboxylic acid{3-[1-(5-methyl-thiazole-2-carbonyl)-3-styryl-1H-indazol-6-yloxy]-phenyl}amide by treatment with 5-methyl-thiazole-2-carboxylic acid and HATU (o-(2-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluoro-phosphate) in DMF and analogous work-up, DDQ treatment and isolation to Example 4(a), step (iv) (50% yield): 1H NMR(DMSO-d6) δ 10.85 (s, 1H), 8.45 (d, 1H, J=9.8 Hz), 8.24 (m, 3H), 7.99–7.62 (m, 6H), 7.54–7.34 (m, 5H), 6.96 (d, 1H, J=8.5 Hz), 2.64 (s, 3H), 2.54 (s, 3H).
