(E)-3-(dimethylamino)-1-(pyridin-3-yl)prop-2-en-1-one (58 mg, 0.327 mmol) and (S)—N-((3-(3-fluoro-4-hydrazinophenyl)-2-oxooxazolidin-5-yl)methyl)acetamide (94 mg, 0.327 mmol) were combined with a solvent, ethanol (3 mL), and then the mixture was slowly heated to reflux, followed by addition of concentrated hydrochloric acid (40 μL). The reaction mixture was maintained under reflux until completion of the reaction as monitored by TLC. Then, the reaction mixture was poured into water and then was extracted with dichloromethane. The dichloromethane layer was rotary evaporated. The residue was purified with column chromatography to afford 55 mg light yellow solid, with a yield of 40.7%, melting point: 83.7-85.9° C., HPLC: 98.2%.
