Reaction Steps

4 M HCl in 1,4-dioxane (6 mL, 24 mmol) was added to a solution of methyl 2-(4-(tert-butoxycarbonyl)-2-((pyridin-3-yloxy)methyl)piperazin-1-yl)thiazole-4-carboxylate (32 mg, 0.074 mmol) in MeOH (1 mL). After stirring overnight, the reaction mixture was concentrated under reduced pressure. The material was dissolved in H2O (20 mL), and the pH was adjusted to ˜2 with concentrated HCl. This was washed with Et2O (3×5 mL, discarded). The aqueous layer was adjusted to pH ˜12 with 1 N NaOH and was extracted with EtOAc (3×20 mL). The combined organics were dried over Na2SO4, filtered, and concentrated under reduced pressure, yielding 5.0 mg (17%) of the title compound. LC-MS: RT=3.41 min, (M+H)+=335.4.
