Water → 1-(1,3-Benzodioxol-5-YL)-3-(4-phenyl-1-piperazinyl)-1-propanone

Participants

Reaction Steps

5-(3-Chloropropionyl)-1,3-benzodioxole (3 g) and N-phenylpiperazine (2.4 g) were dissolved in DMF (20 ml), triethylamine (1.7 g) was then added and the mixture was stirred for 10 hours at room temperature. After completion of the reaction, the reaction mixture was poured into water and extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate and the solvent was distilled off. The residue was crystallized from methanol and the resulting crystals were recrystallized from ethanol to give 5-[3-(4-phenyl-1-piperazinyl)propionyl]-1,3-benzodioxole (4.0 g, 84% yield). The characteristics of this compound are shown in Table 3 as Compound 47.
