실험 절차
1-tert-Butoxycarbonyl-4-(2-methoxyethyl)-3-oxopiperazine (6.6 g) was dissolved in dichloromethane (100 ml), the resulting solution cooled in an ice-bath, and trifluoroacetic acid (145 ml) added. The mixture was stirred at the same temperature for 2 hours. Solvent was evaporated to yield 1-(2-methoxyethyl)-2-oxopiperazine product as a salt with 4 moles of trifluoroacetic acid.
