Reaction Steps
The hydrogen oxalate salt was prepared by mixing the pyrazolidinone and oxalic acid in acetone solution. This gave a white solid which was recrystallised from ethanol to give colourless crystals of 4-dimethylaminomethyl-1-phenylpyrazolidin-3-one hydrogen oxalate (73% melting point 128°-9° C).
