실험 절차

0.06 ml (0.32 mmol) of N,N-diisopropylethylamine is added to a solution of 150 mg (0.16 mmol, 37% purity) of the compound of Example 64A, 32 mg (0.32 mmol) of 2-oxopiperazine, and 97 mg (0.26 mmol) of HATU in 5 ml of THF, and the mixture that is obtained is stirred for 20 hours at room temperature. After the further addition of 32 mg (0.32 mmol) of 2-oxopiperazine, stirring is continued for 5 hours at 60° C. The crude product is separated by means of preparative HPLC (mobile solvent: acetonitrile/water gradient). The title compound is obtained in a quantitative yield.
