Procedure

A mixture of (R)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-3-((S)-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethyl)-1,3-oxazinan-2-one (500 mg, 1.03 mmol), 2,4-dichloropyrimidine (183.7 mg, 1.24 mmol), PdCl2(PPh3)2 (41.2 mg, 5.9%) and aqueous solution of Cs2CO3 (2 mol/L, 2 mL) in 1,4-dioxane (5 mL) was heated to reflux overnight. The reaction was quenched with water. The organic layer was separated, dried, and concentrated to give the residue, which was purified by column chromatography to give (R)-3-((S)-1-(4-(2-chloropyrimidin-4-yl)phenyl)ethyl)-6-(4-fluorophenyl)-6-(3-hydroxypropyl)-1,3-oxazinan-2-one (300 mg, 62%).
