Reaktionsschritte

Following a literature procedure (Harbert et al., J. Med. Chem. 1980, 23, 635-643) p-tolylhydrazine hydrochloride (0.500 g, 3.15 mmol) and 1-carbethoxy-4-piperidone (0.18 mL, 1.17 mmol) were suspended in EtOH (0.880 mL) and heated to reflux for 2 hours. The reaction mixture was removed from heat and allowed to stand overnight at ambient temperature. The resulting mixture was filtered and washed with 50% aqueous EtOH to afford the desired product as a beige powder (259 mg, 86%).
