Reaction Steps
4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of tert-butyl 4-(2-chlorothiazole-4-carbonyl)-3-((pyridin-3-yloxy)methyl)piperazine-1-carboxylate (36 mg, 0.083 mmol) in MeOH (1 mL). After stirring overnight, the reaction mixture was concentrated under reduced pressure, yielding 33.8 mg (99%) of the desired product as a white solid. LC-MS: RT=3.12 min, (M+H)+=338.9.
