Reaction Steps

(S)-2,2-Dimethyl-3-(3-{1-[(S)-4-(1-methyl-2-oxo-1,2-dihydro-pyridin-4-yl)-phenyl]-ethyl}-2-oxo-6-phenyl-[1,3]oxazinan-6-yl)-propionitrile was prepared from (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 following procedures analogous to those described in Example 658 Alternative Method to Prepare 3-((R)-3-((S)-1-(4-bromophenyl)ethyl)-2-oxo-6-phenyl-1,3-oxazinan-6-yl)-2,2-dimethylpropanenitrile. The starting compound, (S)-6-(2-hydroxy-2-methyl-propyl)-3-{(S)-1-[4-(1-methyl-2-oxo-1,2-dihydro-pyridin-4-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 trifluoro-methanesulfonic acid 1-methyl-2-oxo-1,2-dihydro-pyridin-4-yl ester employing the standard conditions, Pd(dppf)Cl2*CH2Cl2, 2 M aqueous Na2CO3 solution, DMF, 90° C., 2 h.
