Procedure

The title compound was prepared from (2S,5R)-tert-butyl 5-(N-(allyloxy)-2-nitrophenylsulfonamido)-2-carbamoyl-3,4-dimethyl-5,6-dihydropyridine-1(2H)-carboxylate (Intermediate 195, 1.36 g, 2.66 mmol) following the procedure described for Intermediate 21. The workup yielded an organic layer that was dried over magnesium sulfate, filtered and concentrated to afford the desired product as a light pink solid (0.82 g, 75%).
