Potassium Iodide → 2-(Ethylamino)-4,5-dimethylthiophene-3-carbonitrile

関与物質

反応手順

To a mixture of 2-(benzylamino)-4,5-dimethylthiophene-3-carbonitrile (302 mg, 2.0 mmol), potassium carbonate (276 mg, 2.0 mmol), and a catalytic amount of potassium iodide in acetonitrile (1 mL) in a 20 mL microwave vial was added ethyl iodide (310 mg, 2.0 mmol). The reaction vial was placed in a microwave reactor for 15 minutes at 165° C. The reaction mixture was dissolved in ethyl acetate and washed with water and brine. The ethyl acetate portion was dried over sodium sulfate and solvent was evaporated under reduced pressure, and the product was purified by prep HPLC using acetonitrile/water as solvent. MS 181 (MH+).
