Dimethyl Sulfoxide → HCID 136377640, compound

Participants

Reaction Steps

Compound 5 (34 mg, 0.055 mmol) was mixed with 1 mL of dimethylsulfoxide, 1 mL of DMF, and 100 μL of methyl iodide at room temperature. After 3 h the reaction mixture was treated with 30 mL of cold water and extracted three times with 10-mL portions of diethyl ether. After neutralization with NaHCO3, chromatographic separation of the aqueous phase on DEAE-Sephadex, using a linear gradient of 0 to 0.8 M TEAB, gave Compound 7 (yield: 10 mg, 28%).
