Synthesis
923034-23-5
55676-22-7
Step 3 Synthesis of 1-(6-chloropyridin-3-yl)ethanone: Dimethyl 2-(6-chloronicotinoyl)malonate (89.8 g, 331 mmol) was dissolved in a solvent mixture of DMSO (445 mL) and water (11 mL), and the reaction was heated for 2.5 hr at 130 °C. After the reaction was completed, the reaction mixture was cooled and poured into H2O/ice (300 mL). The aqueous phase was extracted with EtOAc (4 x 150 mL). The organic phases were combined, washed with brine, dried and concentrated under reduced pressure. The residue was recrystallized by 60% ethanol-water solution to afford the target compound 1-(6-chloropyridin-3-yl)ethanone in a yield of 16.5 g (32% yield) as a yellow solid.
