Conditions

Temperature
60 °C

Procedure

4-(2-(Tetrahydro-2H-pyran-2-yloxy)ethoxy)-3-(trifluoromethyl)phenylboronic acid (8 g) was added to hydrochloric acid (1M in MeOH) and the mixture was heated at 60° C. for 60 minutes. Solvent and HCl was then removed under reduced pressure and residue (5.52 g) was used for next step without further purification.
