Methyl iodide → HCID 67130488, compound

Participants

Reaction Steps

To DMF (80 mL) solution of the compound obtained in Example 137 (5,7 g) was added potassium carbonate (3.6 g) and iodomethane (1.6 mL) at 0° C., and the mixture was stirred for 17 hours at room temperature. The reaction mixture was poured into ice water, and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate, and thereafter the residue obtained by distilling off the solvent under a reduced pressure was purified with silica gel column chromatography (n-hexane:ethyl acetate=5:1), to give the captioned compound (4.8 g, 81%) as an oily product.
