Participants

Reaction Steps

Under nitrogen atmosphere, acetic anhydride (707 μl, 7.49 mmol) and triethylamine (1.39 ml, 9.98 mmol) were added to a dichloromethane (25 ml) solution of 3-(tert-butoxycarbonylmethylamino)pyrrolidine (1.00 g, 4.99 mmol) with cooling with ice, followed by stirring at room temperature for 17 hours. The solvent was evaporated away under reduced pressure, then the resulting residue was subjected to silica gel column chromatography, and the eluate with ethyl acetate gave the entitled compound (1.10 g, 91%) as a pale yellow oil.
