Procedure

The title compound was prepared from N-(allyloxy)-N-((3R,6S)-5-(2-((tert-butyldimethylsilyl)oxy)ethyl)-6-(((tert-butyldimethylsilyl)oxy)methyl)-1,2,3,6-tetrahydropyridin-3-yl)-2-nitrobenzenesulfonamide (Intermediate 283, 6.49 g, 10.11 mmol) according to the procedure described for Intermediate 12. Silica gel chromatography (0%-5% methanol/dichloromethane) afforded the desired product (3.95 g, 86%) as a yellow oil.
