YieldReaction ConditionsOperation in experiment
3.9 g With N-ethyl-N,N-diisopropylamine; HATU; In N,N-dimethyl-formamide; at 20℃; for 12h; A mixture of 6-(trifluoromethyl)indoline [CAS 181513-29-1 ] (2 g, 10.7 mmol), <strong>[170737-95-8]2-(4-chloro-2-methoxyphenyl)acetic acid</strong> [CAS 170737-95-8] (2.36 g, 1 1 .8 mmol), HATU (6.1 g, 16 mmol) and diisopropylethylamine (5.3 mL, 32 mmol) in DMF (50 mL) was stirred at room temperature for 12h. Water was added and the precipitate was filtered off. The residue was taken up with EtOAc. The organic solution was washed with a 10% aqueous solution of K2CO3, brine, dried over MgSO , filtered and the solvent was evaporated under reduced pressure. The residue was purified by chromatography on silica gel (15-40 μιτι, 80 g, heptane/EtOAc gradient 90/10 to 60/40). The pure fractions were combined and the solvent was concentrated under reduced pressure to give 2-(4-chloro-2- methoxyphenyl)-1 -(6-(trifluoromethyl)indolin-1 -yl)ethanone 6a (3.9 g).
1.66 g With benzotriazol-1-ol; 1-ethyl-(3-(3-dimethylamino)propyl)-carbodiimide hydrochloride; triethylamine; In dichloromethane; at 20℃; for 12h; A mixture of <strong>[170737-95-8]2-(4-chloro-2-methoxyphenyl)acetic acid</strong> [CAS 170737-95-8] (1 .55 g, 7.75 mmol) and 6-(trifluoromethyl)indoline [CAS 181513-29-1 ] (1 .45 g, 7.75 mmol), HOBt (2.78 g, 1 1 .6 mmol), EDCI (2.23 g, 1 1 .6 mmol) and triethylamine (2.15 mL, 15.5 mmol) in CH2CI2 (40 mL) was stirred at room temperature for 12 h. Water was added and the layers were separated. The organic layer was washed with water, dried over MgSO4, filtered and the solvent was evaporated under reduced pressure. Purification was carried out by flash chromatography on silica gel (15- 40 μιτι, 120 g, heptane/EtOAc 80/20). The pure fractions were combined and evaporated to dryness to give 2-(4-chloro-2-methoxyphenyl)-1 -(6-(trifluoromethyl)- indolin-1 -yl)ethanone 1a (1 .66 g).
