To a stirred solution of 4-(2-(benzofuran-5-yl)-1-(4-(2-chloroethoxy)phenyl) but-1-enyl)phenol (480 mg, 1.0 eq) in 15 mL MeOH was added 5 mL CH3NH2 (aq) and the mixture was heated at 85° C. for 48 h. The organic solvent was removed in vacuo, water was added to the residue and extracted with EtOAc. The extract was dried, concentrated, and purified by column chromatography to give the desired product (230 mg, 49%, Z/E=1/1). 1H NMR (400 MHz, CDCl3) δ 7.55 (d, J=2.0 Hz, 1H), 7.36 (s, 1H), 7.27 (d, J=8.8 Hz, 1H), 7.15 (d, J=8.8 Hz, 1H), 7.08 (d, J=8.8 Hz, 1H), 7.01 (d, J=8.8 Hz, 1H), 6.87 (d, J=8.8 Hz, 1H), 6.78 (d, J=8.4 Hz, 1H), 6.74 (d, J=8.8 Hz, 1H), 6.69 (d, J=8.8 Hz, 1H), 6.65 (d, J=2.0 Hz, 1H), 6.47 (d, J=8.8 Hz, 1H), 6.41 (d, J=8.4 Hz, 1H), 4.11 (t, J=4.8 Hz, 1H), 3.92 (t, J=4.8 Hz, 1H), 3.01 (t, J=5.2 Hz, 1H), 2.89 (t, J=5.2 Hz, 1H), 2.45-2.54 (m, 5H), 0.89-0.94 (m, 3H); m/z=414[M+1]+.
