Participants

Reaction Steps

4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of tert-butyl 4-(2-fluorobenzoyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate TFA salt (26 mg, 0.050 mmol) in MeOH (1 mL). After 1 h, the reaction mixture was concentrated under reduced pressure and purified by HPLC (5 to 50% MeCN/0.1% TFA in H2O/0.1% TFA gradient). The desired chromatography fractions were concentrated under reduced pressure, dissolved in MeOH (1 mL), and treated with 4 M HCl in 1,4-dioxane. This was concentrated under reduced pressure, yielding 16.3 mg (86%) of the title compound as an off-white solid. LC-MS: RT=3.00 min, [M+H]+=316.3.
