PROCEDURE

实验过程

2-(4-{5-[(2-Phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-pyridin-2-yl}-benzoyl)-cyclopentanecarboxylic acid methyl ester was prepared through a standard Suzuki coupling procedure by mixing 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid (6-bromo-pyridin-3-yl)-amide (prepared using a similar coupling procedure as described above from 2-phenyl-5-trifluoromethyl-oxazole-4-carboxylic acid and 6-bromo-pyridin-3-ylamine.), 2-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-benzoyl]-cyclopentanecarboxylic acid methyl ester, palladium tetrakis(triphenylphosphine) and aqueous sodium bicarbonate solution in toluene and ethanol, and heating this mixture to 160° C. under microwave condition for 20 min. Aqueous workup followed by silica gel chromatography separation gave 2-(4-{5-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-pyridin-2-yl}-benzoyl)-cyclopentanecarboxylic acid methyl ester as light yellow solid. LCMS calcd for C30 H24 F3 N3 O5 (m/e) 563, obsd 564 (M+H).
