Versuchsvorschrift
To a solution of 4-(2,6-dichloro-benzoylamino)-1H-pyrazole-3-carboxylic acid piperidin-4-ylamide hydrochloride salt (Example (237C) 20.6 g, 50 mmol) in water (500 ml) stirring at ambient temperature was added sodium bicarbonate (4.5 g, 53.5 mmol). The mixture was stirred for 1 hour and the solid formed collected by filtration and dried in vacuo azeotroping with toluene (×3) to give the corresponding free base of 4-(2,6-dichloro-benzoylamino)-1H-pyrazole-3-carboxylic acid piperidin-4-ylamide.
