Versuchsvorschrift

A solution of ethyl 2-(5-acetamido-3-(4-fluorophenyl)-4-(phenylethynyl)-1H-pyrazol-1-yl)acetate (620 mg, 1.5 mmol) in ethanol (7 mL) and 25% NaOH (7 mL) was heated to 83° C. for 16 h. The resultant solid was filtered, washed with ethanol and water then dried in vacuo to give 2-(5-amino-3-(4-fluorophenyl)-4-(phenylethynyl)-1H-pyrazol-1-yl)acetic acid as a solid (521 mg), which was used as such in the subsequent step.
