Reaction Steps

A mixture of (4-Chlorophenyl){5-(2-fluoropyridin-4-yl)-2-[1-(tetrahydro-2H-pyran-2-yl)-1H-1,2,4-triazol-3-yl]-3-thienyl}methanol (0.261 g, 0.554 mmol), tert-butyl alcohol (3.9 mL, 41 mmol), 1,4-dioxane (2.6 mL, 33 mmol) and 4.00 M HCl in dioxane (3.66 mL, 16.6 mmol) was heated at 70° C. for 2 h. The mixture was cooled down. A small amount of water was added, followed by the addition of sodium bicarbonate (0.745 g, 8.87 mmol). The mixture was stirred for 10 min and then evaporated in vacuum. The residue was purified by (HPLC to afford 4-chlorophenyl)[5-(2-fluoropyridin-4-yl)-2-(4H-1,2,4-triazol-3-yl)-3-thienyl]methanol as a white solid. LCMS: (AA) ES+ 387.2, 389.1; 1H NMR (300 MHz, d4-methanol) δ: 8.51 (s, 1H), 8.18 (d, J=5.41 Hz, 1H), 7.73 (s, 1H), 7.60-7.44 (m, 3H), 7.37-7.23 (m, 3H), 6.76 (s, 1H).
