EXAMPLE 4 (a) 2-Nitro-4-(3-trifluoromethyl-pyridin-2-yl)-benzoic acid, trifluoroacetic acid salt.; A mixture of 2-chloro-3-trifluoromethyl-pyridine (181 mg, 1 mmol, TCI America), 4-carboxy-3-nitro-phenyl boronic acid (232 mg, 1.1 mmol), Pd(PPh3)4 (81 mg, 0.07 mmol, Aldrich), CsF (380 mg, 2.5 mmol) and water (2 mL) in dioxane (1.5 mL) was heated in a microwave synthesizer at 140 C. for 15 min. The reaction mixture was diluted with water (1 mL) and 1 N NaOH (1 mL), and extracted with diethyl ether (20 mL). The aqueous layer was separated, acidified with 2 N HCl and extracted with EtOAc (2×20 mL). The combined organic extracts were washed with brine, dried over MgSO4 and filtered. The filtrate was evaporated in vacuo and the residue was purified by preparative HPLC (gradient 0.1% trifluoroacetic acid in acetonitrile) to provide the title compound as a brown amorphous solid. MS (ESI, pos. ion) m/z: 313 (M+1). |
