Reaction Steps
The title compound was prepared from (2S,5R)-tert-butyl 5-(N-(allyloxy)-2-nitrophenylsulfonamido)-2-(hydroxymethyl)-4-isopropyl-5,6-dihydropyridine-1(2H)-carboxylate (Intermediate 38, 0.727 g, 1.42 mmol) following the procedure described for Intermediate 19. The desired product was obtained as an off-white foam (0.65 g, 87%).
