Versuchsvorschrift

To a solution of ethyl 4-(cyclohexylamino)-1H-pyrrolo[2,3-b]-pyridine-5-carboxylate (7 mg) in ethanol was added 1M NaOH solution and the mixture was stirred at 90° C. for 18 hours The mixture was cooled to 4° C. and acidified with 1M HCl and extracted with a 4:1 solution of chloroform and methanol. The organic layer was separated, dried over MgSO4 and concentrated under reduced pressure to give 4-(cyclohexylamino)-1H-pyrrolo[2,3-b]pyridine-5-carboxylic acid (6.3 mg) as a white solid.
