Reaction Steps
The title compound was prepared from (2S,5R)-5-(N-(allyloxy)-2-nitrophenylsulfonamido)-1-(tert-butoxycarbonyl)-3,4-dimethyl-1,2,5,6-tetrahydropyridine-2-carboxylic acid (Intermediate 194, 1.48 g, 2.89 mmol) following the procedure described for Intermediate 20. Silica gel chromatography (0%-80% ethyl acetate/hexanes) afforded the desired product as a light yellow foamy solid (1.41 g, 95%).
