Procedure
300 mg (1.04 mmol) of the compound of Example 6A, 301 mg (1.14 mmol) of the compound of Example 24A and 473 mg (1.24 mmol) of HATU were initially charged in 3.6 ml of DMF, 0.36 ml (2.07 mmol) of N,N-diisopropylethylamine was added and the mixture was stirred at RT for two days. The reaction was then directly separated into its components by preparative HPLC (Method 18). This gave 180 mg (31% of theory) of the title compound.
