Reaction Steps

(5S)-5-(Aminomethyl)-3-[4-(1-benzyl-1,2,3,6-tetrahydropyridin-4-yl)-3,5-diflurophenyl]-1,3-oxazolidin-2-one (Intermediate 54) (3.20 g, 8.01 mmol) was reacted with diisopropylethylamine (5.60 ml, 32.04 mmol) and 1,1-dichloroacetone toluenesulfonylhydrazone (2.8 g, 9.6 mmol) as described for Example 3. Chromatography on silica gel with ethyl acetate gave 1.74 g of the title product.
