实验过程

The title compound was prepared from (2S,5R)-tert-butyl 5-(N-(allyloxy)-2-nitrophenylsulfonamido)-2-((tert-butyldimethylsilyloxy)methyl)-3-ethyl-5,6-dihydropyridine-1(2H)-carboxylate (Intermediate 209, 7 g, 11.44 mmol) following the procedure described for Intermediate 18. Silica gel chromatography (30%-90% ethyl acetate/hexanes) afforded the title compound (4.93 g, 87%) as an tan foam.
