Procedure

A mixture of 6-(3-hydroxypropyl)-6-isopropyl-3-((S)-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethyl)-1,3-oxazinan-2-one (40 mg, 0.092 mmol), 4-iodo-1-methylpyridin-2(1H)-one (20 mg, 0.085 mmol), Pd(PPh3)2Cl2 (6 mg, 0.0085 mmol), and Cs2CO3 (2 N, 0.425 mL, 0.85 mmol) in 1,4-dioxane (2 mL) was refluxed for 3 h under N2. The reaction mixture was treated with EtOAc (20 mL) and water (20 mL), and the organic layer was dried and concentrated in vacuo. The residue was purified by preparative HPLC to give two isomers.
