Procedure

Using General Procedure A: 3,3″-dichloro-1′,2′,3′,4′,5′,6′-hexahydro-[2,2′;6′,2″]terpyridine (304 mg, 0.987 mmol), 2-bromomethyl-5-cyano-benzoic acid methyl ester (351 mg, 1.38 mmol), KI (32.7 mg, 0.197 mmol), DIPEA (0.34 mL, 1.97 mmol), and DMF (5 mL) were stirred at 60° C. for 3 h. Purification of the crude material by flash chromatography on silica gel (CH2Cl2/MeOH, 98:2) afforded 5-cyano-2-(3,3″-dichloro-3′,4′,5′,6′-tetrahydro-2′H-[2,2′;6′,2″]terpyridin-1′-ylmethyl)-benzoic acid methyl ester (391 mg, 82%) as a yellow oil. 1H NMR (CDCl3) δ 1.63-1.78 (m, 3H), 2.01-2.14 (m, 1H), 2.18-2.38 (m, 2H), 3.87 (s, 3H), 3.95 (s, 2H), 4.52 (dd, 2H, J=11.4, 1.6 Hz), 6.89 (dd, 2H, J=8.4, 4.9 Hz), 7.38-7.48 (m, 3H), 7.57 (d, 1H, J=1.7 Hz), 8.22-8.32 (m, 3H).
