4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of (R)-tert-butyl 4-(4-hydroxyphenylcarbamoyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate TFA salt (182 mg, 0.335 mmol) in MeOH (1 mL). After 1 h, the reaction mixture was concentrated under reduced pressure, yielding 118 mg (88%) of the title compound as a white solid. LC-MS: RT=2.11 min, [M+H]+=329.1.
