Reaction Steps
Ethyl-1,3-bis (dimethylamino)-propane-2-carboxylate (20.2g) was added in one portion to a boiling mixture of phenyl-hydrazine (10.8g) and sodium isopropoxide (2.3g of sodium) in isopropanol. The solution was boiled under reflux for 30 minutes and the product (13.6g, 62%) was recovered in a manner similar to that described in Example 16. The product was identified as 4-dimethylaminomethyl-1-phenylpyrazolidin-3-one (melting point 117°-8° C) from its infrared spectrum.
