Reaction Steps

To a solution of phenyl boronic acid (1.5 eq.) in Dioxane/H2O (9/1) were added Na2CO3 (4 eq.) and 1-[2-(3-iodo-phenyl)-acetyl]-2-methyl-azetidine-2-carboxylic acid (4-chloro-benzyl)-methyl-amide, compound 8 (1 eq.). The flask was evacuated and backfilled with argon. Then Pd(PPh3)4 was added and the reaction was heated at 90° C. until completion. The crude was partitioned between water and EtOAc. The organic layer was washed with water and brine, dried over MgSO4, filtered and concentrated under reduced pressure. The crude was purified by chromatography on silica gel (elution with Heptane/EtOAc: 100/0 to 20/80) to afford 1-(2-biphenyl-3-yl-acetyl)-2-methyl-azetidine-2-carboxylic acid (4-chloro-benzyl)-methyl-amide.
