Reaction Steps
To a 30 mL vial containing (E)-5-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)styryl)-2H-tetrazole (15 mg, 0.03 mmol) in DMF (2 mL) was added with iodomethane (2.260 μL, 0.04 mmol) and K2CO3 (13.62 mg, 0.10 mmol) and the reaction was stirred at room temperature for 18 h. The reaction was quenched with sat. aq. NH4Cl (15 mL) and extracted with DCM (25 mL). The organic phase was collected (phase separator) and concentrated in vacuo to afford the crude product. The crude product was purified by reverse phase HPLC (neutral condition, 3% 1-propanol in 1-100% CH3CN/H2O) to afford (E)-5-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)styryl)-1-methyl-1H-tetrazole (8 mg, 0.08 mmol, 52% yield) and (E)-5-(4-((6-methoxy-2-(4-methoxyphenyl)benzo[b]thiophen-3-yl)oxy)styryl)-2-methyl-2H-tetrazole (6 mg, 0.01 mmol, 39% yield) both as a white solids.
