Reaction Steps

To a 20 mL vial was added a solution of 4-{4-(4-chlorobenzyl)-5-[1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl]-1,3-thiazol-2-yl}-2-methylpyridine (0.1654 g, 0.365 mmol) in anhydrous tetrahydrofuran (2.000 mL) and methanol (2.000 mL). 4.0 M hydrochloric acid in 1,4-dioxane (1.0 mL, 4.0 mmol) was added and the reaction mixture was allowed to stir at 50° C. for 18 hours. The reaction was cooled to ambient temperature and quenched by the addition of a saturated aqueous solution of sodium bicarbonate (10 mL) then was extracted with EtOAc (10 mL×3). The combined organic layers were dried over anhydrous Na2SO4, filtered and concentrated under reduced pressure. The crude material was purified by HPLC to afford the product (0.0351 g, 39.9%) as a white solid. LC/MS (AA) ES+ 368, 370. 1H NMR (400 MHz, d6-DMSO) δ: 8.73 (s, 1H), 8.56 (d, J=5.2 Hz, 1H), 7.75 (s, 1H), 7.67 (dd, J=5.2, 1.6 Hz, 1H), 7.37-7.32 (m, 4H), 4.65 (s, 2H) 2.55 (s, 3H).
