Hydrochloric Acid → 4-Chlorobenzyl 2-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate dihydrochloride

Participants

Reaction Steps

4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of 1-(4-chlorobenzyl) 4-tert-butyl 2-((pyridin-3-yloxy)methyl)piperazine-1,4-dicarboxylate TFA salt (129 mg, 0.224 mmol) in MeOH (1 mL). After 12 h, the reaction mixture was concentrated under reduced pressure, yielding 95.7 mg (98%) of the desired product as a white solid. LC-MS: RT=4.74 min, [M+H]+=362.1.
