실험 절차

To a solution containing 2.85 (9.01 mmol) of (Pyrrole-2-carbonyl)-N-(benzyl)glycine-t-butyl ester in 50 mL of anhydrous dichloromethane cooled to 0° C. was added 25 mL of TFA dropwise. After 90 minutes an additional 25 mL of TFA was added and allowed to stir for 30 minutes. The mixture was evaporated in vacuo to afford 2.19 g of (Pyrole-2-carbonyl)-N-(benzyl)glycine as a tan solid. FAB MS [M+H] m/z; Calcd. 259, Found 259.
