Reaction Steps

Ethyl 4-(2-(4-(4-((6-(1H-tetrazol-1-yl)pyridin-3-yloxy)methyl)-2H-1,2,3-triazol-2-yl)piperidin-1-yl)pyrimidine-5-carboxylate (0.8 g, 0.00167 mol) (Example 60) was dissolved in MeOH (20 mL). An aqueous solution of NaOH (10 eq., 40 mL) was added and the reaction mixture was heated at 60° C. for three hours. The methanol was removed in vacuo and the remaining reaction mixture was cooled to 0° C. and concentrated HCl was added drop wise until the pH reached 2-3. The aqueous solution was extracted with DCM, dried over sodium sulfate, filtered, and concentrated in vacuo to afford the title compound.
