1,1'-Carbonyldiimidazole → HCID 59654362, compound

Participants

Reaction Steps

To a solution of 0.94 g (3.36 mmol) of 3-(2-trifluoromethoxyphenyl)-benzoic acid in 17 Ml of DMF was added 0.55 g (3.36 mmol) of carbonyldiimidazole (CDI) and the reaction was stirred at RT for 4 h. To the reaction mixture was added. 2.6 g (33.6 mmol) of ammonium acetate and the reaction mixture was stirred over night at RT. The reaction mixture was partitioned between ethyl acetate and water and the organic fraction was washed with brine, dried over MgSO4, filtered and the filtrate was concentrated. The residue was purified by chromatography (silica, 30%, 50% successively EtOAc: hexanes) to give the title compound. Mass Spectrum (ESI) m/e (M+1): 282.2.
