2-(3-tert-Butoxycarbonylaminomethylpyrrolidin-1-yl)ethylamine (1 g) was dissolved in methylene chloride (10 ml) and triethylamine (0.86 ml) was added. Then, a solution of acetyl chloride (0.29 ml) in methylene chlride was dropwise added under ice-cooling. The mixture was stirred at room temperature for 1 hr, and the reaction mixture was concentrated under reduced pressure to give 1-(2-acetylaminoethyl)-3-tert-butoxycarbonylaminomethylpyrrolidine.
