Procedure
Prepared from 5-(4-Methyl-5-trifluoromethyl-isoxazol-3-yl)-thiophene-2-carboxylic acid and thiomopholine 1,1-dioxide by the method described in Example 2 Method B. The reaction mixture was evaporated to a solid, triturated and filtered with the aid of water, then washed with a 1 N aqueous hydrochloric acid solution followed by water. The solid was air dried to afford product as a colorless solid (157 mg, 80%). 1H NMR (DMSO-d6) 2.34 (d, J=1.7, 3 H), 3.27 (obs m, 4 H), 4.00 (m, 4 H), 7.58 (d, J=3.5, 1 H), 7.68 (d, J=4.0, 1 H). 13C NMR (incomplete, F-coupled carbons obscured by baseline noise due to poor solubility) 8.0, ˜44 (br), 51.5, 116.6, 128.0, 130.0, 130.8, 139.6, 158.5, 162.7. 19F NMR −62.2. LC/MS 5.80 min, [M+1]+ 395.
