4-Fluorobenzaldehyde → HCID 57425775, compound

Participants

Reaction Steps

To the solution of 3-(pyridin-3-ylmethyl)pyridine (0.195 g, 1.15 mmol) in THF (5 mL) at −78° C. was added LDA (0.7 mL, 1.8 M) and stirred for 1 h. 4-Fluorobenzaldehyde (0.171 g, 1.37 mmol) in THF (1 mL) was added. The mixture was stirred at −78° C. for 10 min and at −45° C. for 0.5 h. The reaction was quenched with ice and extracted with CH2Cl2. The combined organic layer was dried, filtered, and concentrated to give a solid. The solid was triturated with CH2Cl2 to give 1-(4-fluorophenyl)-2,2-dipyridin-3-ylethanol. 1H-NMR (500 MHz, CDCl3) δ 8.60 (d, 1H, J=1.7), 8.45 (d, 1H, J=1.9), 8.38 (dd, 1H, J=4.7, 1.2), 8.27 (dd, 1H, J=4.6, 1.2), 7.91 (d, 1H, J=7.8), 7.76 (d, 1H, J=8.0), 7.34-7.29 (m, 3H), 7.19 (dd, 1H, J=7.8, 4.9), 7.02 (t, 2H, J=8.8), 5.68 (d, 1H, J=4.9), 5.45 (dd, 1H, J=8.5, 4.8), 4.34 (d, 1H, J=8.8).
