Reaction Steps

4 M HCl in 1,4-dioxane (5 mL, 20 mmol) was added to a solution of tert-butyl 4-(3-bromobenzoyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate (126 mg, 0.264 mmol) in MeOH (1 mL). After stirring for 4 h, the reaction mixture was concentrated under reduced pressure and purified by HPLC (5 to 95% MeCN/0.1% TFA in H2O/0.1% TFA gradient). This gave 80.5 mg (68%) of the desired product as a white solid upon conversion to the dihydrochloride salt. LC-MS: RT=3.91 min, [M+H]+=376.5.
