Versuchsvorschrift

To a solution of 5-(4-benzyl-2-hydroxyphenyl)-1,1-dioxo-1,2,5-thiadiazolidin-3-one (45 mg, 0.141 mmol) in DMF (0.2 mL) is added KOtBu (1.0 M in THF, 0.17 mL, 0.17 mmol). After it is stirred at ambient temperature for 5 min., benzoyl chloride (35 mg, 0.254 mmol) is added. After it is stirred at ambient temperature for 10 min., the reaction is quenched with 1N HCl solution. The residue is then purified by prep. HPLC using CH3CN (0.1% TFA)/water (5-70%) to give the title compound: MS (M−H)−=421.
