実験手順
(S)-N-hydroxy-2,2,4-trimethyl-1,3-dioxolane-4-carbimidoyl chloride (5.5 g, 28.4 mmol) was dissoved in Et2O (150 mL) and methanesulfonyl chloride (2.21 ml, 28.4 mmol) was added. Triethylamine (3.96 ml, 28.4 mmol) was added dropwise and the reaction was stirred at ambient temperature for 1 hour. The resulting solids were filtered and the filtrate concentrated. The residue was purified over silica gel (100% CH2Cl2) to afford (S)-2,2,4-trimethyl-N-(methylsulfonyloxy)-1,3-dioxolane-4-carbimidoyl chloride (4.7 g, 17.3 mmol, 60.9% yield) as an amber oil.
