Reaction Steps

Of the compound from Example 77A, 100 mg (0.29 mmol) were introduced in 3 ml of DMF and admixed with 98.3 mg (0.35 mmol) of the compound from Example 60A, 66.1 mg (0.35 mmol) of EDC, 49 mg (0.35 mmol) of HOBt and 75 μl (0.43 mmol) of N,N-diisopropylethylamine. The mixture was stirred at RT for 30 min and then admixed with 1 ml of 1N hydrochloric acid and purified by preparative HPLC (Method 10). This gave 140 mg (84% of theory) of the title compound.
