Reaction Steps
The title compound (25.2 mg, 68%, white solid) was prepared from methanesulfonic acid 1-[2-(3-chlorophenyl)-2H-tetrazol-5-yl]-ethyl ester (26.4 mg, 0.087 mmol) using potassium carbonate (13.3 mg, 0.096 mmol) and 4-cyclopropyl-5-pyridin-4-yl-2,4-dihydro-[1,2,4]triazole-3-thione (19.0 mg, 0.087 mmol) in acetonitrile (3 mL) at room temperature overnight. The reaction mixture was purified by chromatography using a silica SPE tube (2% methanol in dichloromethane). 1H NMR (CDCl3) δ (ppm): 8.78 (d, 2H), 8.16 (s, 1H), 8.04 (m, 1H), 7.75 (d, 2H), 7.49 (m, 2H), 5.67 (q, 1H), 3.24 (m, 1H), 2.08 (d, 3H), 1.16 (m, 2H), 0.82 (m, 2H).
