Synthesis
N-Chlorosilicate (0.6 mmol, 2.0 equivalent) was added in a single step to a solution of sulfonyl hydrazine (0.3 mmol) in acetonitrile (2 mL). The mixture was stirred at room temperature for 2 hours. The solvent was removed by vacuum evaporation, and the residue was purified by column chromatography (petroleum ether/ethyl acetate) to obtain the target product.
