Versuchsvorschrift

To a solution of 1.3 g (2.814 mmol) 1-[5-(5-Chloro-thiophen-2-yl)-isoxazol-3-ylmethyl]-5-(2-methoxy-ethoxy)-1H-pyrrolo[2,3-c]pyridine-2-carboxylic acid ethyl ester in 30 mL THF and 15 mL MeOH 11.26 mL 1M LiOH solution were added and the mixture was stirred at 50° C. for 3 h. The organic solvents were removed in vacuo, 50 mL of water were added and the pH was adjusted to pH 2 with 1N HCl solution. The desired product precipitated and was filtered, washed with water and dried over P2O5. Yield 1.11 g.
