Reaktionsschritte
A solution of acid 2-7 (380 mg, 1.19 mmole), amine 1-4 (362 mg, 1.19 mmole), BOP (789 mg, 1.79 mmole), NMM (521 μl, 4.76 mmole) and CH3CN (6 ml) was stirred at ambient temperature for 20 h. The reaction was diluted with ethyl acetate and then washed with H2O, sat. NaHCO3, 10% KHSO4, brine, dried (MgSO4) and concentrated. Flash chromotography (silica, EtOAc) gave the ester 2-8 as a white solid.
