In a 50 mL rbf equipped with a magnetic stirrer, 1 g (1 eq, 6.00 mmol) of (E)-ethyl-3-(thiophen-2-yl) acrylate was dissolved in 2 mL of ethanol, followed by the addition of 1.5 mL (5 eq, 30.00 mmol) of hydrazine monohydrate (H2N-NH2.H2O). The mixture was stirred for 3 h at room temperature. TLC, indicative of reaction completion, was performed. Upon cessation of the reaction, the reaction medium was extracted using DCM. The organic layer was washed multiple times with water (H2O), then dried with MgSO4 and concentrated under reduced pressure. The crude product was purified by column chromatography on silica gel, using cyclohexane/ethyl acetate 80/20 as the eluent, yielding a beige powder (52%).
