4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to tert-butyl 4-(benzoyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate TFA salt (89.5 mg, 0.175 mmol). After 12 h, the reaction mixture was concentrated under reduced pressure, yielding 63.8 mg (98%) of the desired product as a white solid. LC-MS: RT=3.05 min, [M+H]+=298.1.
