Ethanol → 6-Chloro-7-(4-(4-(4-(trifluoromethyl)phenyl)pyrimidin-2-ylcarbamoyl)phenoxy)chroman-4-carboxylic acid

Participants

Reaction Steps

Ethyl 6-chloro-7-(4-(4-(4-(trifluoromethyl)phenyl)pyrimidin-2-ylcarbamoyl)phenoxy)chroman-4-carboxylate (50 mg, 0.084 mmol) was diluted with THF (1 mL) followed by the addition of NaOH (502 μL, 0.50 mmol) and ethanol (500 μL). After stirring for 2 hours, the reaction was diluted with ethyl acetate and 2N HCl. The layers were separated and the organic layer was dried over MgSO4, filtered and concentrated. The residue was purified using a 0.5 mm preparative TLC plate eluting with 10% methanol/DCM to yield the desired compound (5 mg, 0.0088 mmol, 10% yield). MS (ESI)=570.1 (M+H)
