Procedure
A sample of 5-[5-(4-chlorophenyl)pent-4-ynyl]-5-(p-tolylsulfonyl)-thiazolidine-2,4-dione (Example 103) was hydrogenated in the presence of Lindlars catalyst in ethanol to give the title compound as a white solid, NMR (CDCl3) δ 2.47 (s, 3H), 5.57 (apparent d of triplets, J=7.3, 11.6 Hz, 1H), 6.42 (br d, J=11.6 Hz, 1H) MS m/Z 499.0495 (M+ calcd. for C21H20ClNO4S2 499.0523).
