DIPEA (2.928 g, 22.66 mmol) was added to a stirred solution of [(biphenyl-4-carbonyl)-amino]-acetic acid (2.892 g, 11.33 mmol) in DMF (30 mL). HOBT (1.835 g, 13.59 mmol) and EDCI.HCl (2.532 g, 13.59 mmol) were then added at room temperature. After 2 minutes, N-Boc-piperazine (3.381 g, 24.22 mmol) was added and the resulting mixture was stirred overnight. The reaction mixture was diluted with cold water and the product was extracted with ethyl acetate. The ethyl acetate layer was washed with saturated brine solution, dried over sodium sulphate and concentrated in vacuo to afford 1.7 g (37.5% yield) of 4-{2-[(biphenyl-4-carbonyl)-amino]-acetyl}-piperazine-1-carboxylicacid tert-butyl ester. LC-MS purity: 82.06%
