Potassium Carbonate → (S)-6-amino-5-ethynyl-N-[methyl(oxo)phenyl-lambda6-sulfanylidene]nicotinamide

Participants

Reaction Steps

To a solution of (S)-6-amino-N-[methyl(oxo)phenyl-λ6-sulfanylidene]-5-[(trimethylsilyl)ethynyl]nicotinamide (308 mg, 0.83 mmol) in 20 mL THF/methanol (1:1 ratio) at 0° C. was added K2CO3 (344 mg, 2.5 mmol) added. After 7 minutes the solution was decanted from the solids and partitioned between EtOAc and H2O. The EtOAc layer was washed with brine, dried with anhydrous Na2SO4 and rotary evaporated. The brown oil was purified by chromatography (silica gel, CHCl3/EtOAc) to give the title compound as a white solid (193 mg, 78%).
