실험 절차

The title compound was prepared in analogy to the procedure described for step E2 using 2-bromo-5-[(4-chlorophenyl)-hydroxy-methyl]-1-isopropyl-1H-imidazole-4-carboxylic acid ethyl ester (intermediate B) and 5-amino-1-methylpiperidin-2-one (ChemBridge, free base was made from the purchased HCl salt) as starting materials. The crude reaction mixture was diluted with EtOAc and washed with aqueous NaHCO3 solution and brine. tr: 1.07 min (LC-MS 2); ESI-MS: 511.1 [M+H]+ (LC-MS 2); 1H-NMR (DMSO-d6, 400 MHz) δ ppm 7.42 (m, 2H), 7.30 (m, 2H), 6.28 (NH, br, 1H), 4.85-5.00 (m, 1 H), 4.25 (quin, 2 H), 3.15-3.05 (m, 2H), 2.84-2.75 (m, 1H), 2.72 (d, 3H), 2.38-1.85 (m, 4H), 1.75-1.58 (m, 1), 1.45 (d, 3 H), 1.24 (t, 3 H), 0.83 (t, 3H).
