The 1H NMR data for compound 5 given in reference 18 contained a second, incorrect assignment for the peak at 1.41 ppm. The correct 1H NMR data are:

1H NMR (300 MHz, CDCl3): δ = 8.19 (s, 1 H), 8.15 (d, J = 8.3 Hz, 1 H), 7.86 (dd, J = 8.3, 1.1 Hz, 1 H), 7.75 (td, J = 7.2, 1.5 Hz, 1 H), 7.53 (td, J = 7.9, 1.1 Hz, 1 H), 6.53 (s, 1 H), 5.79 (d, J = 2.3 Hz, 1 H), 5.35 (d, J = 2.3 Hz, 1 H), 3.80 (m, 2 H), 1.65 (m, 2 H), 1.41 (m, 2 H), 0.94 (t, J = 7.2 Hz, 3 H).
