Prepared from 5-(4-Methyl-5-trifluoromethyl-isoxazol-3-yl)-thiophene-2-carboxylic acid and 4-amino-3-chloropyridine by the method described in Example 2 Method B reversing the order of addition such that solid acid chloride was added to a THF solution of triethylamine and pyridine derivative. The reaction mixture was evaporated to a solid, triturated and filtered with the aid of water, then washed with a saturated aqueous NaHCO3 solution followed by water to afford product as a colorless solid (80 mg, 83%). 1H NMR (CDCl3) 2.40 (s, 3H), 7.59 (d, J=4.0, 1H), 7.73 (d, J=4.0, 1H), 8.46 (s, 3H), 8.59 (s, 1H). 13C NMR 7.9, 114.5, 114.7, 118.6 (q, J=271), 129.0, 129.7, 135.2, 140.4, 141.0, 149.4, 149.6, 155.6 (q, J=40), 157.6, 159.3. 19F NMR −63.1.
