실험 절차
To a solution of piperazine-1,2,4-tricarboxylic acid 1-tert-butyl ester 4-(9H-fluoren-9-ylmethyl)ester 2-methyl ester (2.03 mmol) in DMF (4.0 mL) was added diethylamine (5%) and the resulting solution was stirred at room temperature overnight. The reaction mixture was concentrated in vacuo and purified using ethyl acetate/methanol (10%). ESI-MS m/z: 245(M+1), UV retention time: 0.78 min.
