Hydrochloric Acid → N-Methyl-N-phenyl-2-((pyridin-3-yloxy)methyl)piperazine-1-carboxamide dihydrochloride

Participants

Reaction Steps

4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of tert-butyl 4-(N-methyl-N-phenylcarbamoyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate TFA salt (28.1 mg, 0.052 mmol) in MeOH (1 mL). After 12 h, the reaction mixture was concentrated under reduced pressure, yielding 16.9 mg (81%) of the desired product as a yellow solid. LC-MS: RT=3.83 min, [M+H]+=327.1.
