2,2,2-Trifluoroethanol → HCID 86682930, compound

Participants

Reaction Steps

To the stirred solution of 2,2,2-trifluoro-ethanol (0.051 ml, 0.69 mmol) in 4 ml of DMF, was added NaH (28 mg, 0.69 mmol) portion wise at 0° C. The mixture was stirred for 30 min at room temperature and then a solution of 2,6-dichloro-4-phenyl-quinoline-3-carboxylic acid ethyl ester (200 mg, 0.58 mmol) in 2 ml dry DMF was added. The resulting reaction mixture was stirred for 5 h at room temperature. The reaction mixture was quenched with saturated aqueous NH4Cl solution and then diluted with further water, and extracted with EtOAc. The organic layer was washed with brine, dried over anhydrous Na2SO4 and concentrated in vacuo to give a crude residue which was purified by flash column chromatography (5% ethyl acetate in hexane) to obtain 6-chloro-4-phenyl-2-(2,2,2-trifluoro-ethoxy)-quinoline-3-carboxylic acid ethyl ester (140 mg, 59%) as off white solid. LC-MS: 410 (M+H)+.
