To a stirred solution of 4-(1-(4-(2-chloroethoxy)phenyl)-2-(2,3-dihydrobenzofuran-5-yl)but-1-enyl)phenol (500 mg, 1.0 eq) in 20 mL MeOH, 10 mL CH3NH2 (aq) was added and heated at 85° C. for 24 h. The 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 (Z/E=1/1). 1H NMR (400 MHz, CDCl3) δ 7.10 & 7.01 (d, J=8.8 Hz, 2H), 6.92 (s, 1H), 6.83 (d, J=8.4 Hz, 1H), 6.82 & 6.74 (d, J=8.8 Hz, 2H), 6.79 & 6.75 (d, J=8.8 Hz, 2H), 6.57 (d, J=8.4 Hz, 1H), 6.51 & 6.45 (d, J=8.8 Hz, 2H), 4.51 (t, J=8.4 Hz, 2H), 4.10 & 3.96 (t, J=4.8 Hz, 2H), 3.09 (t, J=8.8 Hz, 2H), 3.01 & 2.93 (t, J=4.8 Hz, 2H), 2.54 & 2.50 (s, 3H), 2.39-2.46 (m, 2H), 0.90-0.94 (m, 3H); m/z=416 [M+1]+.
