Procedure

4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of tert-butyl 4-(6-fluorobenzo[d]thiazol-2-ylcarbamoyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate TFA salt (122 mg, 0.203 mmol) in MeOH (1 mL). After 1 h, the reaction mixture was concentrated under reduced pressure, yielding 83.9 mg (90%) of the title compound as a white solid. LC-MS: RT=4.61 min, [M+H]+=388.1.
