2-Chloro-5-(chloromethyl)thiophene Use and Manufacturing
At 0 ° C under nitrogen protection conditions, to a solution of compound 6-2 (500 mg, 3.37 mmo 1) in tetrahydrofuran (10 mL) thionly chloride(482 mg, 4.05 mmol) was added dropwise. After completion of the dropwise addition, the mixture was heated at 50 ° C for 3 hours, and the reaction was monitored by TLC plate. The solvent was evaporated under reduced pressure to obtain 480 mg of a yellow liquid (yield: 85.5 percent), Used directly for the next step.
