Reaction Steps
Lithium hydroxide (15.5 mg, 0.649 mmol) was added to a solution of methyl 2-(4-(tert-butoxycarbonyl)-2-((pyridin-3-yloxy)methyl)piperazin-1-yl)thiazole-4-carboxylate (0.282 g, 0.649 mmol) in THF (2 mL), MeOH (2 mL), and H2O (1 mL). After 5 h, 4M HCl in 1,4-dioxane (0.200 mL) was added, and the reaction mixture was concentrated under reduced pressure. The material was used without further purification. LC-MS: RT=6.35 min, [M+H]+=421.7.
