실험 절차

To a stirred solution of N-biphenyl-4-yl-malonamic acid (0.091 g, 0.00036 mole) in DMF (1 mL) was added DIPEA (0.211 g, 0.0016 mole), HOBt (0.048 g, 0.00036 mole) and EDCI.HCl (0.125 g, 0.00065 mole). After 2 minutes (2-tert-butyl-phenyl)-piperidin-4-yl-amine dihydrochloride (0.1 g, 0.00033 mole) was added and the resulting mixture was stirred overnight. The reaction mixture was then diluted with cold water and the resulting precipitate was isolated by filtration. Purification by column chromatography using silica gel 60-120 mesh (1% methanol in chloroform) afforded 0.062 g (40%) of N-biphenyl-4-yl-3-[4-(2-tert-butyl-phenylamino)-piperidin-1-yl]-3-oxo-propionamide. LC-MS purity: 470.27 (M+1)+, 96.38%, 1H NMR (DMSO-d6): δ 7.8-7.6 (m, 6H), 7.5 (t, 2H), 7.3 (d, 1H), 7.1 (d, 1H), 7.0 (t, 1H), 6.8 (d, 1H), 6.6 (t, 1H), 4.3 (d, 1H), 3.9 (d, 2H), 3.7 (s, 1H), 3.6 (s, 2H), 3.2 (t, 1H), 2.9 (t, 1H), 2.0 (t, 2H), 1.5 (t, 1H), 1.4 (s, 9H).
