YieldReaction ConditionsOperation in experiment
64% With copper(l) iodide; In N,N-dimethyl-formamide; at 100℃; for 6h; To a stirred solution of 5-bromo-2-chloro-4-iodopyridine (40 g, 126.2 mmol, 1 eq) in DMF (400 mL) was added methyl 2,2-difluoro-2-(fluorosulfonyl)acetate (32.1 mL, 252.5 mmol, 2 eq) followed by CuT (48.2 g, 252.5 mmol, 2 eq). The resulting mixture was heated at 100 C for 6 h. TLC analysis indicated formation of a non-polar spot. The reaction mixture was diluted with water (200 mL), filtered through a celite pad and washed with n-pentane (2 x 500 mL) and followed by cold water (3 x 1000 mL). Organic layers were separated, dried over Na2SO4 and concentrated under reduced pressure at 30 C resulted 5-bromo-2-chloro-4-(trifluoromethyl)pyridine (21 g, 64% yield) as a liquid compound. TLC: 5% EtOAc in pet ether; Rf: 0.7
55.2% With copper(l) iodide; In N,N-dimethyl-formamide; at 100℃; for 6h;Inert atmosphere; To a stirred solution of 5-bromo-2-chloro-4-iodopyridine (20.0 g, 63.09 mmol, 1.0 eq) in DMF (200 mL), methyl 2,2-difluoro-2-(fluorosulfonyl)acetate (16.15 mL, 126.18 mmol, 2.0 eq) and Cul (24.02 g, 126.18 mmol, 2.0 eq) were added at RT under argon atmosphere and the reaction mixture was heated to 100C for 6h. TLC analysis indicated a non-polar spot. The reaction mixture was diluted with water (200 mL) and filtered off and washed with w-pentane (1L) and cold water (3L). The separated organic layer was dried over sodium sulfate and concentrated under reduced pressure at 30C. The crude compound was purified by column chromatography (Silica gel, 100-200 mesh) using 5% EtOAc in pet ether as an eluent to afford the title compound (9.0 g, 55.2%) as a liquid compound. TLC: 5% EtOAc in pet ether; Rf: 0.7
44% With copper(l) iodide; In N,N-dimethyl-formamide; at 100℃; for 6h;Inert atmosphere; To a stirred solution of 5-bromo-2-chloro-4-iodopyridine (20.0 g, 63.09 mmol) in DMF (200 mL), methyl 2,2-difluoro-2-(fluorosulfonyl)acetate (16.15 mL, 126.18 mmol) and Cul (24.02 g, 126.18 mmol) were added at RT under argon atmosphere. The reaction mixture was heated to 100 C for 6 hours. The reaction mixture was diluted with water (200 mL) filtered off and washed with w-pentane (2 X 500 mL) and cold water (3 X 1000 mL). The separated organic layer dried over with sodium sulfate and concentrated under reduced pressure at 30 C to give the crude compound. That was purified by column chromatography (5% pet ether: EtO Ac) that resulted in the title compound (9.0g, 44%) as a liquid compound. TLC: 5% EtO Ac in pet ether. LCMS [M+H]+ = 261.0 g/mol.
