Procedure
2,2-Dimethyl-3-(3-{(S)-1-[4-(1-methyl-6-oxo-1,6-dihydro-pyridin-3-yl)-phenyl]-ethyl}-2-oxo-(S)-6-phenyl-[1,3]oxazinan-6-yl)-propionitrile was prepared from (S)-6-(2-hydroxy-2-methylpropyl)-3-((S)-1-(4-(1-methyl-6-oxo-1,6-dihydropyridin-3-yl)phenyl)ethyl)-6-phenyl-1,3-oxazinan-2-one following procedures analogous to those described Example 71 Method 2 to prepare 3-((R)-3-((S)-1-(4-bromophenyl)ethyl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)-2,2-dimethylpropanenitrile. (S)-6-(2-hydroxy-2-methyl-propyl)-3-{(S)-1-[4-(1-methyl-6-oxo-1,6-dihydro-pyridin-3-yl)-phenyl]-ethyl}-6-phenyl-[1,3]oxazinan-2-one, is obtained from coupling (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 with 5-iodo-1-methyl-1H-pyridin-2-one by the action of Pd(PPh3)4 and 2 M aqueous Na2CO3 solution in a mixture of methanol and dioxane (1:3) at 80° C. The compound that had been obtained as a foam was dissolved in a small amount of ethyl acetate and stirred overnight at rt. The solid was filtered by suction, washed with a small amount of diethylether and dried. Melting point: 143-145° C.
