Procedure

(3R,9aR)-tert-Butyl 3-(3-cyano-4-fluoro-2,5-dimethylphenyl)hexahydropyrazino[2,1-c][1,4]oxazine-8(1H)-carboxylate was prepared in an analogous fashion to that described for the synthesis of (3R,9aS)-tert-butyl 3-(3-cyano-4-fluoro-2,5-dimethylphenyl)hexahydropyrazino[2,1-c][1,4]oxazine-8(1H)-carboxylate starting from 6-fluoro-2-methyl-3-((3R,9aR)-octahydropyrazino[2,1-c][1,4]oxazin-3-yl)benzonitrile.
