Reaction Conditions:
with water in ethanol;Reflux;
Steps:
2.4 General procedure for the synthesis of 5-amino-1-phenyl-1H-pyrazole-4-carboxylic acid derivatives (6)
General procedure: Intermediates 13 6 was synthesized according to the literature by ML Bender [28]. Intermediates 5 was dissolved in a solution of 15 ethanol and 16 potassium hydroxide and refluxed for 2h. After cooling, the pH of the mixture was adjusted to 5-6by the dropwise addition of 10% 17 HCl solution to give an intermediate 13 6, which was filtered under vacuum and recrystallized from ethanol to give the pure products.
