Versuchsvorschrift

The title compound was prepared from (2S,5R)-tert-butyl 5-(N-(allyloxy)-2-nitrophenylsulfonamido)-2-(hydroxymethyl)-3,4-dimethyl-5,6-dihydropyridine-1(2H)-carboxylate (Intermediate 193, 1.68 g, 3.38 mmol) following the procedure described for Intermediate 19. The workup yielded organics that were dried over magnesium sulfate, filtered and concentrated crude material to afford a light orange foam (1.48 g, 86%).
