Procedure

600 mg (1.43 mmol) of the compound from Example 25A in dimethylformamide (29.0 ml) were admixed at RT with 654 mg (1.72 mmol) of HATU and 0.55 ml (498 mg, 3.16 mmol) of N,N-diisopropylethylamine, and the mixture was stirred for 30 min. Subsequently, 158 mg (1.58 mmol) of N′-hydroxycyclopropanecarboximidamide were added and the mixture was stirred at RT overnight. The reaction solution was heated to 120° C. and stirred at this temperature for 1 h. The reaction solution was subsequently purified directly by means of preparative HPLC. Yield: 315 mg (45% of theory)
