Reaction Steps
The title compound was prepared from (2S,5R)-5-(N-(allyloxy)-2-nitrophenylsulfonamido)-1-(tert-butoxycarbonyl)-3-cyclopropyl-1,2,5,6-tetrahydropyridine-2-carboxylic acid (Intermediate 241, 2.28 g, 4.35 mmol) following the procedure described for Intermediate 20. The desired product was obtained as an orange foam (1.07 g, 47%).
