Reaction Steps

Prepared as above from 464.9 mg (1.11 mmol) of the pyridyl ketone and 1.00 g (2.21 mmol) of the Wittig salt. Flash chromatography with 15% MeOH--CH2Cl2 afforded 526.0 mg (92%) of the product (E/Z=~4:1 by 1H NMR): 1H NMR (DMSO) δ 8.66 (s, 1H), 8.52(m, 1H), 8.40 (dd, J=4.5, 1.1 Hz, 1H), 8.36 (d, J=1.9 Hz, 1H), 8.01 (d, J=8.2 Hz, 2H), 7.47 (m, 2H), 7.29 (d, J=8.1 Hz, 2H), 6.20 (t, J=7.4 Hz, 1H), 3.57 (br t, J=4.4 Hz, 4H), 3.28 (br dt, J=~6.2, 5.8 Hz, 2H), 2.30 (br s, 6H), 2.02 (m, 4H), 1.63 (br t, J=6.6 Hz, 2H), 1.40 (m, 4H); FDMS 519 (M+1). 97.5% pure by HPLC.
