To a solution of (3R,6S)-3-(N-(allyloxy)-2-nitrophenylsulfonamido)-6-(methoxymethyl)-N,N-dimethyl-1,2,3,6-tetrahydropyridine-4-carboxamide (Intermediate 141, 1.346 g, 2.96 mmol) and potassium carbonate (2.456 g, 17.77 mmol) in acetonitrile (50 mL) was added benzenethiol (1.825 mL, 17.77 mmol) and stirred at rt overnight. The solvent was evaporated then the crude mixture was redissolved in DCM and a little bit MeOH, filtered, loaded onto silica gel. The crude product was purified via flash chromatography (0-20% MeOH/DCM) and dried under high-vacuum to obtain the desired product (0.725 g, 91%) as a pale yellow oil.
