Procedure

The title compound was synthesized in a manner analogous to Example 475, step I via (4S,55)-tert-butyl 4-((2-chloropyridin-4-yl)methyl)-5-(hydroxymethyl)-2,2-dimethyloxazolidine-3-carboxylate in the presence of TBSCl and imidazole and was used without further purification. Step 2: (4S,5S)-tert-butyl 5-((tert-butyldimethylsilyloxy)methyl)-4-((2-chloro-6-methylpyridin-4-yl)methyl)-2,2-dimethyloxazolidine-3-carboxylate
