New Pyrazol Derivatives. IV. Preparation and Cyclization of Some Acceptor-Substituted N-(Pyrazol-3-yl)-thioureas

3-Aminopyrazol-4-carboxylic acid derivatives (1,2) were transformed by reaction with different isothiocyanates R2NCS to N-(pyrazol-3-yl)-N'-substituted thioureas (5,6).Ethyl 3-amino-1-benzylpyrazol-4-carboxylate reacts with CSCl2 to form ethyl
