According to the same procedure as example 1, step E described, 4-(2-(2-chlorobenzofuran-5-yl)-1-(4-(2-chloroethoxy)phenyl)but-1-enyl)phenol (70 mg, 1.0 eq, made by example 11, step D) was reacted with pyrrolidine (1 mL) in MeOH (3 mL) under reflux to give the desired product (51 mg, 68%, Z/E=1/2.6) as a yellow solid. 1H NMR (400 MHz, CDCl3) δ 7.24 (s, 1H), 7.20 (d, J=9.2 Hz, 1H), 7.09 & 7.06 (d, J=8.4 Hz, 2H), 7.00 (d, J=8.8 Hz, 1H), 6.78 & 6.72 (d, J=8.2 Hz, 2H), 6.68 (d, J=8.6 Hz, 2H), 6.46 & 6.45 (s, 1H), 6.41 & 6.27 (d, J=8.4 Hz, 2H), 4.10 & 3.89 (t, J=5.8 Hz, 2H), 2.94 & 2.83 (t, J=6.2 Hz, 2H), 2.68 & 2.61 (m, 4H), 2.49 (q, J=7.4 Hz, 2H), 1.84 & 1.81 (m, 4H), 0.91 (t, J=7.4 Hz, 3H); m/z=488[M+1]+.
