tei -Butyl 4-(4,4,5,5-tetramethyl-1 ,3,2-dioxaborolan-2-yl)-3,6-dihydropyridine-1(2/-/)- carboxylate (Intermediate 7) (395 mg, 1.28 mmol) and Cs2C03 (1.03 g, 3.19 mmol) were added to a solution of 2-iodo-6-methoxypyridine (Intermediate 8) (300 mg, 1.28 mmol) in 1 ,4-dioxane (10 mL) and the resulting mixture was degassed under a nitrogen atmosphere for 20 min. (9,9-Dimethyl-9/-/-xanthene-4,5-diyl)bis(diphenylphosphane) (Xantphos, 36 mg, 0.06 mmol) and palladium(ll) acetate (29 mg, 0.13 mmol) were added and the resulting reaction mixture was stirred at 80 C for 18 h. The solvents were removed in-vacuo and residue was partitioned between H20 (80 mL) and EtOAc (60 mL). The aqueous layer was further extracted with EtOAc (60 mL) and the combined organic layers were dried (Na2S04) and the solvent was removed in-vacuo. The residue was purified by column chromatography (normal phase neutral activated alumina, 10 % to 12 % EtOAc in hexane) to give tert- butyl 6- methoxy-3′,6′-dihydro-2,4′-bipyridine-T(2’/-/)-carboxylate (310 mg, 84 %) as a gum. LCMS (System 3, Method D): m/z 291 (M+H)+ (ESI +ve), at 5.73 min, 202 nm.

DMSO (0.36and 2,2,6,6-tetramethyl-3,5-heptanedione (4 il, 0.019 mmcl) were then added. The reaction was heated at 40 C for three hours. The cooled mixture was diluted with EtOAc and washed thrice witha solution of 9:1 saturated NH4CI: NH4OH and then thrice with water and then brine. The organic layer was dried over Na2SO4, filtered and concentrated. The well dried solid was dissolved in methylene chloride and passed through a short silica plug, which removed the small amount of unreacted amine. The filtrate was condensed to give white solid, which was purified by automated flash chromatography system in 50-80 % methylene chloride/hexanes. Isolated yield = 61%, ee =96%. Recrystallization to enhance ee was carried out by heating a solution of 15.8 mg of purified product in 1.0 ml of isopropanol. Overall Yield = 59 %, ee = 98.5 %1H NMR (CDCI3, 400 MHz) :5 8.16 (d, J = 1.9 Hz, 2H), 7.56 (d, J = 1.9 Hz, 2H), 7.35 – (t, J = 7.8 Hz, 1H),7.30 (d, J = 8.7 Hz, 1H), 6.04 (dd, J = 32.7, 8.0 Hz, 2H), 5.29 -5.02 (dm, 1H), 4.65 -4.46 (m, 3H), 3.87- 3.74 (m, 1H), 3.70 (s,3H), 3.66 – 3.49 (m, 1H).
