Versuchsvorschrift

To a solution of 3-[5-({[1-(4-fluorophenyl)-1H-pyrazolo[3,4-c]pyridine-4-carbonyl]-amino}-methyl)-pyridine-2-sulfonyl]-propionic acid methyl ester (100 mg, 0.2 mmol) in THF (5 mL) was added a freshly prepared 8% solution of sodium ethoxide (200 μL, 0.2 mmol) in ethanol. The mixture was stirred for 15 minutes and was monitored for the disappearance of starting material by TLC (EtOAc). The mixture was then concentrated to dryness under a stream of nitrogen. The mixture was again diluted with THF and then N-chlorosuccinimide (55 mg, 0.41 mmol) was added. After 15 minutes, 2-methoxyethylamine (0.100 mL, 1.15 mmol) was added in one portion. After 15 minutes, the mixture was diluted with saturated ammonium chloride and extracted with EtOAc (3×10 mL). The combined organic layers were washed with brine (2×10 mL), dried over magnesium sulfate, filtered and concentrated. The crude material was purified by silica gel chromatography eluting with methanol-EtOAc (0:100, then 0.5:99.5, then 1:99, then 2:98). The material from the column was purified a second time by using preparative silica gel TLC eluting with methanol-EtOAc (1:9). The material from the plate was triturated with EtOAc-ether-hexanes to afford the title compound.
