Methyl iodide → HCID 178485934, compound

Participants

Reaction Steps

To a solution of the compound (0.23 g) obtained in Example 242 in DMF (7.0 mL) were added potassium tert-butoxide (0.079 g) and methyl iodide (0.055 mL) at 0° C. The mixture was stirred at room temperature for 12 hr, diluted with ice water, and extracted with ethyl acetate. The extract was washed with water, 1N aqueous potassium hydrogen sulfate solution and saturated brine, dried and concentrated under reduced pressure. The residue was separated and purified by silica gel column chromatography (solvent gradient; 50→100% ethyl acetate/hexane) to give the title compound (0.17 g, 70%) as a white powder.
