실험 절차

To a solution of (rac.)-2-phenylpropionic acid (46 mg, 0.30 mmol) and diisopropylethylamine (0.15 mL, 0.9 mmol) in acetonitrile (2 mL) is added benzotriazole-1-yl-oxy-tris-(dimethylamino)-phosphonium hexafluorophosphate (322 mg, 0.73 mmol) at RT. After stirring 30 min at RT, 1-[4-(4-amino-thiazol-2-yl)-piperidin-1-yl]-2-(2,5-dimethyl-phenyl)-ethanone (100 mg, 0.30 mmol) is added to the reaction mixture. After stirring overnight at RT, the solvent is evaporated and the residue is purified by flash chromatography on silica gel (ethylacetate/cyclohexane 1:1) to give N-(2-{1-[2-(2,5-dimethyl-phenyl)-acetyl]-piperidin-4-yl}-thiazol-4-yl)-2-phenyl-propionamide (Compound No. I.g.141, 19 mg, 13.4%). 1H-NMR (400 MHz, CDCl3): δ=1.46-1.39 (m, 1H), 1.52 (d, 3H), 1.68-1.56 (m, 1H), 1.89-1.83 (m, 1H), 2.01-1.97 (m, 1H), 2.15 (s, 3H), 2.19 (s, 3H), 2.73-2.67 (m, 1H), 3.18-2.92 (m, 2H), 3.59 (s, 2H), 3.68-3.63 (q, 1H), 3.78-3.71 (m, 1H), 4.65-4.62 (m, 1H), 6.91-6.82 (m, 2H), 7.02-6.98 (m, 1H), 7.31-7.15 (m, 5H), 7.42 (s, 1H), 8.05 (br, 1H). MS: m/z=462 (M+1).
