Procedure

A mixture of 3-(2-(3,4-dimethoxyphenyl)propan-2-yl)-4-(4-fluorophenyl)-1H-1,2,4-triazole-5(4H)-thione (200 mg, 0.54 mmol) and K2CO3 (111 mg, 0.80 mmol) in acetone (15 mL) was stirred for 30 min at room temperature. 2-Chloro-6-fluorobenzyl chloride (206 μL, 1.61 mmol) was added to the reaction mixture, and the resulting mixture was refluxed for 2 h. The reaction mixture was cooled to room temperature, filtered through Celite, and concentrated. Purification by flash chromatography [Hex/EtOAc, 1:4 to 1:1] afforded the title product (230 mg, 0.45 mmol, 83%). 1H NMR (400 MHz, CDCl3) δ 7.20-7.12 (m, 2H), 6.95-6.91 (m, 1H), 6.84-6.80 (m, 2H), 6.68 (d, 1H), 6.54 (d, 1H), 6.50 (dd, 1H), 6.45-6.40 (m, 2H), 4.45 (s, 2H), 3.87 (s, 3H), 3.77 (s, 3H), 1.65 (s, 6H); MS (EI) m/z 516 (MH+).
