반응 단계
A mixture of 22-4 (300 mg, 1.0 mmol), 19-2a (329 mg, 1.0 mmol), NMM (430 gL, 4.0 mmol), and CH3CN (5 mL) at ambient temperature was treated with BOP (650 mg, 1.5 mmol). After 20 h the reaction mixture was diluted with EtOAc and then washed with 10% KHSO4 and brine, dried (MgSO4) and concentrated. Flash chromatography (silica, 40% EtOAc/hexanes) gave 22-5 as a white solid. TLC Rf =0.16 (silica, 40% EtOAc/hexanes);
