Procedure

At ambient temperature, a solution containing cis-2-butyl-3-[2-(4-methoxy-phenyl)-vinyl]-benzofuran (0.400 g, 1.31 mmol) in EtOAc (5 mL) and 10% palladium on carbon (200 mg) was stirred under H2 (atmospheric conditions). The reaction was filtered and the filtrate concentrated to the title compound as a clear oil. 1H NMR (DMSO-d6) δ 0.83 (t, 3H), 1.20 (sextet, 2H), 1.37 (quintet, 2H), 2.49-2.52 (m, 2H, with DMSO), 2.78-2.85 (m, 4H), 3.68 (s, 3H), 6.78 (d, 2H), 7.03 (d, 2H), 7.17-7.21 (m, 2H), 7.41-7.43 (m, 1H), 7.54-7.56 (m, 1H). IR (KBr) 2950, 1610, 1510, 1450 and 1250 cm−1. mass spectrum (EI) m/z 308 (M+). Anal. Calcd. for C21H24O2: C, 81.78; H, 7.84; N, 0.00. Found: C, 81.55; H, 7.57; N, 0.10.
