58 mg (0.173 mmol) of the compound of Example 98A and 75 mg (0.198 mmol) of HATU were dissolved in 1 ml of DMF, and 24 mg (0.198 mmol) of 4-N,N-dimethylaminopyridine (DMAP) were added slowly. 50 mg (0.165 mmol) of the compound of Example 11A were then added. The reaction mixture was stirred at RT for about 16 h and then separated into its components by preparative HPLC (Method 36). Pooling of the product fractions, evaporation and drying of the residue under high vacuum gave 76 mg (75% of theory) of the title compound.
