실험 절차

DIPEA (170 mg, 1.3 mmol) was added to a stirred solution of 1-phenyl-1H-imidazole-4-carboxylic acid (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, 2-amino-1-[4-(2,5-difluoro-phenoxy)-piperidin-1-yl]-ethanone hydrochloride (prepared according to Step 1 and 5 of the General Scheme) (98.5 mg, 0.32 mmol) was added and the resulting mixture was stirred at ambient temperature overnight. The reaction mixture was diluted with cold water, extracted with ethyl acetate, dried over sodium sulfate and concentrated under reduced pressure. The residue obtained was purified by washing with ether to afford 63.5 mg (49.6% Yield) of 1-phenyl-1H-imidazole-4-carboxylic acid {2-[4-(2,5-difluoro-phenoxy)-piperidin-1-yl]-2-oxo-ethyl}-amide. LC/MS [M+H]+: 441.17. 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), 7.44 (t, 1H), 7.3 (m, 1H), 6.84 (m, 1H), 4.8 (m, 1H), 4.2 (d, 2H), 4.0 (bs, 1H), 3.8 (bs, 1H), 3.7 (bs, 2H), 3.5 (bs, 1H), 2.1 (t, 2H), 1.8 (d, 2H).
