---|---|---|
74% | With acetic acid; for 4h;Reflux; | General procedure: Compound 1 (10 mmol) was dissolved in acetic acid (30 mL), andlevulinic acid (15 mmol) was added to the stirred solution which wasthen refluxed for 4 h. After cooling to room temperature, the mixturewas poured into water (200 mL) and then the solution was treated with30% sodium hydroxide to slight acidity (pH = 5-6). The precipitatedsolid was filtered off, recrystallised from ethanol and dried in vacuo togive compound 2. |

69.5% | In methanol; at 20℃; for 2h; | General procedure: The equimolar aldehyde 3a?3d (1 mmol) and substituted phenylhydrazine 5a?5s (1 mmol) weremixed in CH3OH (10 mL) and stirred at room temperature [18]. After about 2 h, the reaction wascompleted (monitored by TLC). The residual crude was purified via silica gel column chromatogramusing a gradient mixture of petroleum ether and ethyl acetate to obtain the pure target compounds6a?6ai (in 45?80percent yield). |

80% | In ethanol; at 20℃; for 4h; | General procedure: The hydrazones 1-10 were prepared by a condensation reaction between phenylhydrazine derivatives and imidazole or benzimidazole carbaldehydes [45-47]. In a 25-mL Erlenmeyer flask, 1mmol of 1-methylbenzimidazole-2-carbaldehyde or 1-methylimidazole-2-carbaldehyde and 1mmol of phenylhydrazine derivative (phenylhydrazine, 4-methoxyphenylhydrazine, 3,4-dimethylphenylhydrazine, 4-chlorophenylhydrazine and (4-benzylphenyl)hydrazine) were dissolved in 3ml of ethanol. The reaction mixture was stirred at room temperature for 4h, and then filtered and air-dried. The resulting residue was then purified by recrystallization in a mixture of ethanol/DMSO to give the pure product. |
