With pyridine; hydrazine hydrate; In ethanol; for 10h;Reflux; | General procedure: To a mixture corresponding ester (9a-n, 5.0 mmol) and hydrazine monohydrate (15.0 mmol) in ethanol, catalytic amount of pyridine (0.5 mL) was added and refluxed for 10 h. The reaction was monitored by TLC. After the completion of the reaction, ethanol was evaporated from the mixture, water was added and extracted using ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and evaporated under vacuum to get the crude mass. Finally, the products 10a-n were purified using column chromatography. (Yield 80-85%). |

With triethylamine; In dichloromethane; at 0℃; for 2h; | General procedure: To a cooled solution of the 10a-n (3.0 mmol) in dichloromethane, triethylamine (3.0 mmol) was added at 0 C followed by the addition of the corresponding 12a-c (3.0 mmol). The reaction mixture was stirred at 0 C for 2 h. After the completion of the reaction, water was added and the reaction mixture was extracted using ethyl acetate. The organic layer was washed with 10% sodium bicarbonate solution and finally with brine solution. It was dried over anhydrous sodium sulfate and evaporated under vacuum. The products 13a-q was purified by column chromatography. |
