Reaktionsschritte

A mixture of thiomorpholine-4-carboxylic acid (4-{[2-(2-methyl-2H-indazol-6-ylcarbamoyl)-phenylamino]-methyl}-pyridin-2-yl)-amide (50 mg, 0.1 mmol) and sodium periodate (43 mg, 0.2 mmol) in MeOH/water (3:1, 4 mL) was stirred overnight at rt. The reaction was partitioned between EtOAc and brine and the organic phase dried, filtered and concentrated in vacuo to give 1-oxo-thiomorpholine-4-carboxylic acid (4-{[2-(2-methyl-2H-indazol-6-ylcarbamoyl)-phenylamino]-methyl}-pyridin-2-yl)-amide (30 mg, 58%) as a solid; 1H-NMR (300 MHz, d6-DMSO) 10.14 (1H, s), 9.37 (1H, s), 8.25 (1H, s), 8.17 (1H, d), 8.10 (1H, s), 7.96 (1H, t), 7.82 (1H, s), 7.71-7.74 (1H, m), 7.63 (1H, d), 7.23-7.32 (2H, m), 6.96-6.98 (1H, m), 6.67 (1H, t), 6.54 (1H, d), 4.45 (2H, d), 4.13 (3H, s), 3.99-4.04 (2H, m), 3.66-3.74 (2H, m), 2.84-2.93 (2H, m), 2.65-2.70 (2H, m); m/z (LC-ES+) 518 [M+H]+.
