Methyl iodide → HCID 483539, compound

Participants

Reaction Steps

To a partial suspension of N-[(imidazol-2-yl)methyl] 3-phenylsulfonyl-5-chloroindole-2-carboxamide (Example 35) (42 mg, 0.1 mmol) in 1:1 methanol/tetrahydrofuran (4 mL) was added iodomethane (0.05 mL, 0.8 mmol). The reaction was stirred for three days at room temperature. The solvents were removed under reduced pressure, aq. NaHCO3 added and the product extracted into ethyl acetate/methanol. The organic layer was dried (Na2SO4), filtered, and the solvents evaporated. The residue was purified by chromatography and the product eluted with 3% methanol/chloroform. Appropriate fractions were combined, the solvents evaporated, and the residue triturated with methylene chloride to give pure product.
