Reaction Steps

4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to tert-butyl 4-(4-methoxyphenylcarbamoyl)-3-(pyridin-3-ylmethyl)piperazine-1-carboxylate (76.0 mg, 0.141 mmol). After stirring overnight, 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 (6 mL). This was concentrated under reduced pressure, yielding 30.5 mg (54%) of the desired product as an off-white solid. LC-MS: RT=2.11 min, [M+H]+=327.1.
