Procedure

1.00 g of 1,3-dimethyl-5-phenyl-4-(2-oxazolin-2-yl)aminopyrazole is dissolved in a little methanol, and ethanolic hydrochloric acid is added thereto until a weakly acid reaction is obtained. The resulting solution is evaporated to dryness, and the evaporation residue is washed several times with diethylether to obtain 1.15 g of 1,3-dimethyl-5-phenyl-4-(2-oxazolin-2-yl)aminopyrazole hydrochloride, mp 211° to 213°.
