Trifluoroacetic acid → 5-Chloro-4-((7,7-dimethyl-5,6,7,8-tetrahydronaphthalen-2-yloxy)methyl)-2-fluorobenzoic acid

Participants

Reaction Steps

To a solution of tert-butyl 5-chloro-4-((7,7-dimethyl-5,6,7,8-tetrahydronaphthalen-2-yloxy)methyl)-2-fluorobenzoate (220 mg, 0.53 mmol) in DCM (5 mL) was added trifluoroactic acid (5 mL). After stirred at room temperature for 3 h, the reaction mixture was concentrated under reduced pressure and the residue was used in next step without further purification (0.22 g, crude). LCMS (ESI) m/z: 361.0 [M−H]+.
