Participants

Reaction Steps

A mixture of (R)-1-((S)-1-(4-bromophenyl)ethyl)-4-(2-hydroxyethyl)-4-phenyl piperidin-2-one (30 mg, 0.072 mmol), 4-fluorophenylboronic acid (15 mg, 0.11 mmol), Pd(Ph3P)2Cl2 (5 mg), and aqueous Cs2CO3 (0.1 mL, 2M) in 1,4-dioxane (2 mL) was stirred and heated at reflux for 2 h. The organic phase was separated, and concentrated to give the crude product, which was purified by preparative TLC to give (R)-1-((S)-1-(4′-fluorobiphenyl-4-yl)ethyl)-4-(2-hydroxyethyl)-4-phenylpiperidin-2-one (3.0 mg, 10%). LC-MS Method 2, tR=2.103 min, m/z=440.1. 1H NMR (CDCl3): δ 1.46 (d, 3H), 1.83 (m, 1H), 2.01 (m, 3H), 2.32 (m, 1H), 2.59 (dd, 1H), 2.96 (m, 1H), 3.11 (dd, 1H), 3.34 (m, 1H), 3.49 (m, 1H), 6.02 (q, 1H), 6.89 (m, 2H), 7.06 (m, 2H), 7.22 (m, 2H), 7.31 (m, 4H), 7.40 (m, 2H).
