実験手順

A solution of (2S,6S,13aS,14aR,16aS,Z)-ethyl 6-(tert-butoxycarbonylamino)-2-hydroxy-5,16-dioxo-1,2,3,5,6,7,8,9,10,11,13a,14,14a,15,16,16a-hexadecahydrocyclopropa[e]pyrrolo[1,2-a][1,4]diazacyclopentadecine-14a-carboxylate (22.1 g, 44.8 mmol) and DABCO (8.5 g, 76.7 mmol) in toluene (88 mL) was stirred at room temperature. To this solution was added a solution of 4-bromobenzene-1-sulfonyl chloride 17.2 g, 67.2 mmol) in toluene (44 mL). After the addition was complete the reaction mixture was quenched with 10% aqueous sodium carbonate (110 mL) and the mixture stirred for 15 min. Tetrahydrofuran (44 mL) was added and the mixture was washed with 0.5 M HCl, water, and then saturated aqueous sodium chloride. The organic layer was dried over anhydrous magnesium sulfate, filtered, and evaporated under reduced pressure and dried to provide the title compound (27.7 g, 87% yield), which was used without further purification.}
