Reaction Steps

4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of 4-tert-butyl 1-phenyl 2-((pyridin-3-yloxy)methyl)piperazine-1,4-dicarboxylate TFA salt (108.2 mg, 0.205 mmol) in MeOH (1 mL). After 1 h, the reaction mixture was concentrated under reduced pressure, yielding 72.3 mg (91%) of the desired product as a white solid. LC-MS: RT=3.89 min, [M+H]+=314.1.
