実験手順

To a solution of (2S)-tert-butyl 5-(N-(allyloxy)-2-nitrophenylsulfonamido)-4-(2-amino-2-oxoethyl)-2-carbamoyl-5,6-dihydropyridine-1(2H)-carboxylate (Intermediate 175, 1.36 g, 2.52 mmol) and potassium carbonate (1.742 g, 12.60 mmol) in acetonitrile (20.0 mL) at 0° C. was added benzenethiol (1.389 g, 12.60 mmol). The mixture was stirred at room temperature for 15 hours. The reaction mixture was concentrated and the resulting residue was triturated with DCM. The solids were removed by filtration. The filtrate was concentrated to a pale yellow film, which was subjected to silica gel column eluting with 0-50% MeOH/DCM to give a pale yellow solid, 330 mg, 36.9%.
