Procedure
Free base of the title compound is prepared in 97% yield (510 mg, clear colorless oil) from 2-((5-bromo-6-(2,2,2-trifluoroethoxy)pyridin-3-yl)methyl)isoindoline-1,3-dione (770 mg, 1.8 mmol, Step-2) by the similar manner in Step-4 of Amine-24. The obtained amine is suspended in 4M hydrochloric acid in dioxane (3 mL), and the mixture is stirred for 30 minutes at room temperature to give a white precipitate. The precipitate is collected by filtration, washed with dichloromethane, dried in vacuo to give 540 mg (94% yield) of the title compound as a white solid.
