Reaction Steps
The title compound was prepared from (2S,5R)-tert-butyl 5-(N-(allyloxy)-2-nitrophenylsulfonamido)-2-((tert-butyldimethylsilyloxy)methyl)-3-cyclopropyl-5,6-dihydropyridine-1(2H)-carboxylate (Intermediate 239, 3.19 g, 5.11 mmol) following the procedure described for Intermediate 18. The desired product was obtained as a tan foam (2.35 g, 90%).
