反応手順
To a stirring solution of (9.20 g, 46.9 mmoles) benzoylmercaptoacetic acid and (5.41 g, 46.9 mmoles) N-hydroxysuccinimide in (100 mL) dioxane was added a solution of (9.70 g, 47 mmoles) dicyclohexylcarbodiimide in (40 mL) dioxane. The reaction was stirred 12 hours followed by cooling to 4° C., filtering, and rotavapping off the dioxane to a white solid. The solid was triturated with cold isopropanol, filtered, and dried in vacuo yielding 10.8 g, 78% benzoylmercaptoacetyl-N-hydroxysuccinimide. 200 mg was recrystallized from 500 mg in hot ethyl acetate.
