S-(2-bromo-5-fluorophenyl) N,N-dimethylcarbamothioate

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 51.30 g of S-(2-bromo-5-fluorophenyl) dimethylthiocarbamate were dissolved in 700 ml of MOH, 494 ml of a 1 N aqueous sodium hydroxide solution were added and the reaction mixture was heated for 2 h under reflux. After cooling, the MOH was removed in vacuo, 200 ml of water were added and the mixture was extracted three times with 150 ml each of DCM. Subsequently, the mixture was acidified to pH=1 with concentrated hydrochloric acid and extracted four times with 200 ml each of EA. The combined organic phases were dried over sodium sulfate and the solvent was removed in vacuo. 37.80 g of the title compound were obtained as a pale yellow oil. were added the reaction mixture was heated for 2 h under reflux After cooling the MOH was removed in vacuo, 200 ml of water were added the mixture was extracted three times with 150 ml each of DCM extracted four times with 200 ml each of EA The combined organic phases were dried over sodium sulfate the solvent was removed in vacuo
