Sodium hydride (80% dispersion in mineral oil, 93 mg, 3.10 mmol) was added to a solution of N-(triphenylmethyl)-5-(toluene-4-sulfonyl)-thiazolidine-2,4-dione [(VI), from Example 34, 1.06 g, 2.07 mmol) in dry DMF (9 mL) at 0° C. under a dry N2 atmosphere. After 20 min, [3-(4-chlorophenyl)-prop-2-ynyl]-bromide [(IX), from Example 21, 0.52 g, 2.27 mmol] was added and the reaction mixture was stirred an additional 20 min at 0° C. Saturated aqueous NH4Cl (60 mL) was added, followed by water (60 mL). After stirring for 10 min, the solid was filtered, washed with water and triturated with petroleum ether to provide the title compound as a grey solid (1.16 g, 90%): mp 221°-223° C.; NMR (CDCl3): δ7.80 (d, J=8.2 Hz, 2H, ArH), 7.45 (d, J=7.5 Hz, 6H, CPh3H), 7.35 (d, J=8.2 Hz, 2H, ArH), 7.14 (m, 11H, Ar'H, CPh3H), 6.98 (d, J=8.5 Hz, 2H, Ar'H), 3.29 (d, J=16.7 Hz, 1H, CH2), 3.12 (d, J=16.7 Hz, 1H, CH2), 2.46 (s, 3H, CH3).
