To a stirred solution of 4-(1-(4-(2-chloroethoxy)phenyl)-2-(thiophen-3-yl)but-1-enyl)phenol (0.3 g, 1.0 eq) in 10 mL MeOH was added 10 mL MeNH2 (30% in water). The mixture was refluxed at 80° C. overnight, and purified by column chromatography with CH2Cl2:MeOH(NH3)=10:1 to give the desired product (185 mg, 63% yield, Z/E=1/1). 1H NMR (400 MHz, CDCl3) δ 7.00-7.12 (m, 3H), 6.90-6.95 (m, 1H), 6.80-6.89 (m, 2H), 6.72-6.79 (m, 2H), 6.68-6.72 (m, 1H), 6.58 (d, J=8.8 Hz, 1H), 6.53 (d, J=8.8 Hz, 1H), 4.09 (t, J=5.2 Hz, 1H), 3.99 (t, J=5.2 Hz, 1H), 3.00 (t, J=5.2 Hz, 1H), 2.94 (t, J=5.2 Hz, 1H), 2.40-2.54 (m, 5H), 0.98 (t, J=5.2 Hz, 3H); m/z=380[M+1]+.
