Reaction Steps

Sulfuric acid is added to a solution of 4-Chloro phenyl hydrazine hydrochloride (1 equiv.) in dioxane and stirred for 5 min. at RT. N-cyclopropyl piperidone (1 equiv.) is added and the mixture is heated at 80° C. for 2 h. After completion, as monitored by TLC, the reaction mixture is concentrated under reduced pressure and basified to pH 10 using 10% aqueous KOH solution. The reaction product is extracted with EtOAc, dried over anhydrous sodium sulfate and concentrated under reduced pressure using rotary evaporator to provide the desired compound.
