Sodium Hydroxide → 2'-(Trifluoromethoxy)[1,1'-biphenyl]-3-carboxylic acid

Participants

Reaction Steps

A solution of 0.3 g (4.19 mmol) of ethyl-3-(2-trifluoromethoxyphenyl)-benzoate and 8.3 Ml (8.3 mmol) of a 1N solution of NaOH in 12.5 Ml of methanol was stirred 18 h at RT. The reaction mixture was concentrated and the Ph was adjusted to Ph=2 with 1 N HCl solution. The mixture was extracted with ethyl acetate (EtOAc) and the organic fraction was dried over MgSO4, filtered and the filtrate was concentrated to give the title compound as a white solid that was used without further purification.
