実験手順

A mixture of 4-iodo-1-methylpyridin-2(1H)-one (0.909 g, 3.76 mmol), (S)-6-(2-hydroxy-2-methylpropyl)-6-phenyl-3-((S)-1-(4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)ethyl)-1,3-oxazinan-2-one (1.5 g, 3.13 mmol), 2 M aq Cs2CO3 (3 mL, 6 mmol), and PdCl2(PPh3)2 (0.201 g, 0.282 mmol) in 1,4-dioxane (15 mL) was refluxed under N2 for 2 hours. The reaction mixture was filtered, and the filtrate was extracted with EtOAc. The combined organic layer was washed with brine, dried over Na2SO4 and concentrated to obtain the crude compound, which was purified by preparative HPLC and chiral HPLC to obtain (S)-6-(2-hydroxy-2-methylpropyl)-3-((S)-1-(4-(1-methyl-2-oxo-1,2-dihydropyridin-4-yl)phenyl)ethyl)-6-phenyl-1,3-oxazinan-2-one (399 mg, 28%). LC-MS and 1H NMR (CD3OD) were the same as those of product made by Method 1. The compound was recrystallized using below methods.
