Reaction Steps

To a solution of p-toluenesulfonylmethyl isocyanide (6.1 g) and 1,1,3,3-tetramethylguanidine (8.3 mL) in tetrahydrofuran (18 mL) and isopropyl alcohol (18 mL) was added dropwise a solution of 2-nitro-1-phenylpropyl acetate (7.0 g) in tetrahydrofuran (3 mL) and isopropyl alcohol (3 mL), and the mixture was stirred at room temperature for 4 hr. Water was added to the reaction mixture, and the mixture was extracted with a mixed solvent of ethyl acetate and tetrahydrofuran. The extract was washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give the title compound as a white solid (yield 6.1 g, 63%).
