4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of tert-butyl 4-(2-morpholinooxazole-4-carbonyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate TFA salt (165 mg, 0.277 mmol) in MeOH (1 mL). After stirring overnight, the reaction mixture was concentrated under reduced pressure to give 105.5 mg (85%) of the title compound as a white solid. LC-MS: RT=2.70 min, [M+H]+=374.0.
