Methyl iodide → HCID 22258075, compound

Participants

Reaction Steps

To a stirred solution of Example 1 Part B compound (112 mg, 0.243 mmol) in DME (1 mL) under argon at room temperature was added sodium hydride (60% mineral oil dispersion, 9.7 mg, 0.24 mmol). After 30 min, methyl iodide (15 μL, 0.24 mmol) was added, the reaction mixture was stirred for 18 h and then diluted with saturated ammonium chloride solution. The mixture was extracted three times with Et2O. The organic extracts were combined, washed once with water, once with brine, dried (MgSO4) and evaporated. Purification by flash chromatography on silica gel provided the title compound as a colorless oil, 67 mg (58% yield). LC/MS gave the correct molecular ion [(M+H)+=475] for the desired compound.
