2-chloro-4,5-difluorobenzenesulfonyl chloride

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

実験手順: The reaction and aftertreatment were conducted in the same manner as in Example 14b by using the N-(2,4-dimethoxybenzyl)pyrimidin-4-amine (150 mg, 0.611 mmol) prepared in Example 14a, 2-Chloro-4,5-difluorobenzenesulfonyl chloride (302 mg, 1.22 mmol), 1,4-diazabicyclo[2.2.2]octane (137 mg, 1.22 mmol) and acetonitrile (5.0 mL), to yield the title compound (58.8 mg, 21%) as a colorless oil.

反応条件: temp:150.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 2-Chloro-4,5-difluorobenzenesulfonyl chloride (300 mg) was added to a solution of sodium sulfite (306 mg) and sodium bicarbonate (153 mg) in water (4 mL). The mixture was heated to 150° C. in a sealed microwave vial for 400 seconds and allowed to cool. The mixture was treated with bromoacetic acid (253 mg) in water (1 mL), and heated to 150° C. for 300 seconds then allowed to cool, following which the precipitate was removed by filtration and dried in vacuo to give the desired compound (132 mg). The material was used without further purification. to cool heated to 150° C. for 300 seconds to cool was removed by filtration dried in vacuo

実験手順: Synthesized as described for 3 using 2-chloro-4,5,-difluorobenzenesulfonyl chloride (500 mg; 2.02 mmol), methyl 3-aminothiophene-2-carboxylate (382 mg; 2.43 mmol), 4-dimethylaminopyridine (62 mg; 0.51 mmol), pyridine (10 mL), and anhydrous dichloromethane (10 mL). The crude product was purified by automated silica gel chromatography (Biotage®) using ethyl acetate/hexanes as eluant system (0 to 20% v/v over 7 column volume gradient elution) to yield the title product as a white solid (249 mg).
