0.12 ml (0.71 mmol) of N,N-diisopropylethylamine as well as 0.5 ml of DMF are added to a solution of 75 mg (0.24 mmol) of the compound of Example 20A, 32 mg (0.26 mmol) of 4-imidazolinone-hydrochloride, and 126 mg (0.33 mmol) of HATU in 1 ml of THF, and the mixture that is obtained is stirred for 16 hours at room temperature. The reaction mixture is diluted with acetonitrile, filtered over a Millipore spray filter, and separated by means of preparative HPLC (mobile solvent: acetonitrile/water gradient). 71 mg (78% of theory) of the title compound is obtained.
