실험 절차

A stirring solution of 24-3 (250 mg, 1.1 mmol), 19-2a (368 mg, 1.1 mmol), NMM (442 mg, 4.4 mmol), and CH3CN (5 mL) at ambient temperature was treated with BOP (483 mg, 1.1 mmol). After 20 h the reaction mixture was diluted with EtOAc and then washed with H2O, sat. NaHCO3, 10% KHSO4 and brine, dried (MgSO4) and concentrated. Flash chromatography (silica, 40% EtOAc/hexanes) gave 24-4 as a white solid. TLC Rf =0.46 (silica, 50% EtOAc/hexanes);
