(S)-Ethyl[N-({5-[(3-hydroxyphenyl)ethynyl]pyridin-3-yl}carbonyl)-S-phenylsulfonimidoyl]acetate (73 mg, 0.16 mmol) in anhydrous MeOH (1.5 mL) was added N,N-diethylethylenediamine (0.12 mL, 0.84 mmol) dropwise. The reaction mixture was heated at 30° C. for 4 hours. The reaction mixture was evaporated and the residue was partitioned between EtOAc and saturated aqueous NaHCO3. The organic layer was washed once with brine, dried (anhydrous Na2SO4), concentrated. The residue was purified by chromatography (silica gel, 50:1 CHCl3:MeOH to 10:1 CHCl3:MeOH). The product containing fractions were concentrated to give the title compound as a foamy solid (50 mg, 59%).
