4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to tert-butyl 4-(5-phenylfuran-2-carbonyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate TFA salt (58.9 mg, 0.102 mmol). After 1 h, the reaction mixture was concentrated under reduced pressure, yielding 39.6 mg (89%) of the desired product as a white solid. LC-MS: RT=4.63 min, [M+H]+=364.1.
