2-Aminothiazole → 4-[(3'S)-3-(3,5-dichlorophenyl)-2'-oxo-1,3'-bipyrrolidin-1'-yl]-2,6-difluoro-N-(thiazol-2-yl)benzenesulfonamide

Temperatur

0 °C

Synthesized according to General Procedure 12, Method B. To a solution of 2-aminothiazole (35 mg, 0.35 mmol) in acetonitrile (0.4 mL) at 0° C. was added 2-tert-butyl-1,1,3,3-tetramethylguanidine (61 mg, 0.35 mmol) dropwise and the reaction mixture stirred at 0° C. for 10 min. 4-[(3′S)-3-(3,5-dichlorophenyl)-2′-oxo-1,3′-bipyrrolidin-1′-yl]-2,6-difluorobenzene-1-sulfonyl chloride (60 mg, 0.12 mmol) was added and the reaction mixture was stirred at RT for 16 hours. The reaction mixture was diluted with DMSO, filtered and purified by reverse phase HPLC using 5%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA) to afford 4-[(3′S)-3-(3,5-dichlorophenyl)-2′-oxo-1,3′-bipyrrolidin-1′-yl]-2,6-difluoro-N-(thiazol-2-yl)benzenesulfonamide. LC/MS (10%-99% CH3CN (0.035% TFA)/H2O (0.05% TFA)), m/z: M+1 obs=573.3; tR=1.32 min.
