実験手順

0.07 ml (0.43 mmol) of N,N-diisopropylethylamine is added to a solution of 75 mg (0.21 mmol, 90% purity) of the compound of Example 22A, 23 mg (0.23 mmol) of 2-oxopiperazine, and 113 mg (0.30 mmol) of HATU in 2 ml of THF, and the mixture that is obtained is stirred for 3 hours at room temperature. The reaction mixture is separated by means of preparative HPLC (mobile solvent: acetonitrile/water gradient), and the title compound is obtained in a quantitative yield (87 mg).
