反応手順

To the solution of 2-(2-(5-(4-chlorophenyl)-2,3-dihydro-1,3,4-thiadiazol-2-yl)phenoxy)acetamide is added DIEA (2.0 mmol) and 2,4,6-tri-fluorobenzoyl chloride (2.0 mmol) and the reaction mixture is stirred for 12 hours at room temperature. After evaporation of the solvent, the residue is purified by automated chromatography (hexane/EtOAc) to give 2-{2-[5-(4-chloro-phenyl)-3-(2,4,6-trifluoro-benzoyl)-2,3-dihydro-[1,3,4]thiadiazol-2-yl]-phenoxy}-acetamide: 1H NMR (400 MHz, CDCl3) δ 7.43 (s, 1H), 7.27 (d, J=8.8, 2H), 7.15 (m, 2H), 7.14 (d, J=8.4 Hz, 2H) 6.99 (bs, 1H), 6.84 (t, J=6.4 Hz, 3H), 6.66 (d, J=8.4 Hz, 1H), 6.53 (t, J=8.0 Hz, 2H), 5.29 (bs, 1H), 4.47 (d, J=1.6 Hz, 2H); LC/MS: (ES+) 506.2 (M+1)+.
