Reaction Steps

A mixture of (S)-4-allyl-4-(4-fluorophenyl)-1-((S)-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethyl)piperidin-2-one (120 mg, 0.260 mmol), 5-bromo-1-methylpyridin-2(1H)-one (80 mg, 0.31 mmol), PdCl2(Ph3P)2 (12 mg) □ Cs2CO3 (0.4 mL, 0.8 mmol□ in 1,4-dioxane (3 mL) was heated to reflux for 2 h. The mixture was diluted with EtOAc, and washed with water. The organic phase was separated, and concentrated to give the product, which was purified by TLC to afford 5-(4-((S)-1-((S)-4-allyl-4-(4-fluorophenyl)-2-oxopiperidin-1-yl)ethyl)phenyl)-1-methylpyridin-2(1H)-one (45 mg, 39%). 1H NMR (CDCl3): δ 1.42 (t, 3H), 1.91 (m, 1H), 2.03 (m, 1H), 2.24 (m, 2H), 2.39 (m, 1H), 2.49 (d, 1H), 2.96 (m, 2H), 3.49 (s, 3H), 4.92 (m, 2H), 5.38 (m, 1H), 5.99 (m, 1H), 6.11 (m, 1H) □ 6.52 (m, 1H) □ 6.62 (m, 1H), 6.89 (m, 4H), 7.11 (m, 3H), 7.23 (m, 2H), 7.32 (m, 1H), 7.49 (m, 1H).
