Reaktionsschritte

A mixture of 3-hydroxy-3-(4-methoxyphenyl)propanoic acid (13.7 mg, 0.07 mmol), (Z)-tert-butyl (4-acetamido-3,5-dichlorobenzylamino)(amino)-methylenecarbamate (26.3 mg), PyBop (36.4 mg), and triethylamine (0.01 mL) in dichloromethane (0.35 mL) was stirred at room temperature for 12 h. The crude reaction mixture was purified directly by preparative TLC eluting with 30% ethyl acetate/70% hexanes to give the title compound as a clear sticky oil (30 mg, 77% yield). 1H NMR (400 MHz, CDCl3) δ 1.48 (m, 9 H) 2.21 (s, 3 H) 2.70 (m, 2 H) 3.78 (m, 3 H) 4.55 (m, 2 H) 4.95 (m, 1 H) 6.80-7.00 (m, 3 H) 7.24-7.38 (m, 4 H), 9.10 (m, 1 H), 12.30 (m, 1 H). HPLC retention time: 2.493 min (method A). MS (ESI) (M+H)+ 553.08.
