Reaction Steps

To a solution of 3,4-diphenyl-1H-pyrazole-5(4H)-thione (0.5 g, 1.981 mmol) in DMF (5 mL), were added 1-bromo-2-methoxyethane (0.275 g, 1.981 mmol) and K2CO3 (0.274 g, 1.981 mmol) at room temperature. After stirring for 4 h, the reaction was poured into water and extracted with ethyl acetate. The organic extract was dried over MgSO4 and concentrated under reduced pressure. The resulting residue was purified by column chromatography to give the title compound (0.45 g). LCMS m/z=311.2 [M+H]+; 1H NMR (400 MHz, DMSO-d6) δ ppm 3.23 (s, 3H), 3.12-3.54 (m, 4H), 7.22-7.49 (m, 10H), 13.2 (s, 1H).
