DIPEA (170 mg, 1.3 mmol) was added to a stirred solution of [(1-phenyl-1H-imidazole-4-carbonyl)-amino]-acetic acid (prepared from Intermediate 68 by means of Step 3 of the General Scheme) (55 mg, 0.29 mmol) in DMF (5 mL) followed by HOBt (43 mg, 0.32 mmol) and EDCI (140 mg, 0.7 mmol). After 2 minutes of stirring, 4-(2-chloro-phenoxy)-piperidine hydrochloride (98 mg, 0.32 mmol) was added and the resulting mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with cold water and the precipitate was collected. The precipitate was purified by recrystallisation from a mixture of 20% EtOAc in hexane (15 mL) and MeOH (0.1 mL) to afford the 80 mg (62.5% Yield) of 1-phenyl-1H-imidazole-4-carboxylic acid {2-[4-(2-chloro-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide. LC/MS [M+H]+: 439.15, 98.75%. 1H NMR (300 MHz, DMSO-d6): δ 8.4 (s, 1H), 8.3 (s, 1H), 8.08 (t, 1H), 7.8 (d, 2H), 7.6 (t, 2H), 7.48 (m, 2H), 7.34 (m, 2H), 7.1 (t, 1H), 4.8 (m, 1H), 4.2 (d, 2H), 3.8 (t, 2H), 3.6 (t, 2H), 2.0 (d, 2H), 1.8 (d, 2H).
