Procedure

This compound was synthesized from 9-(2-thienyl)-8-nonenoic acid (1.19 g, 5 mmol) by a hydrogenation reaction using Pd/C (120 mg). Crystallization afforded the product (1.05 g, 88%) as white crystals (mp 32°-33° C.); IR: 3400-2500, 1715, 705 cm-1 ; 1H-NMR: 1.35 (m, 12H), 2.35 (t, 2H), 2.85 (t, 2H), 6.95 (m, 3H), 10.35 (bs, 1H). Anal. Calcd. for C13H20SO2 : C, 64.96, H, 8.39%; Found: C, 64.81, H, 8.43%.
