Procedure

50 mg (90 μmol) of Example 2A are dissolved with 41 mg (117 μmol) of the caesium salt of Boc-valine (prepared from Boc-valine by General Procedure 1) in 10 ml of DMF. Stirring at 50° C. for 42 h is followed by concentrating and the residue is purified by preparative HPLC (method 1a). The appropriate fractions are concentrated and dried under high vacuum to obtain 26 mg (39% of theory) of the protected title compound.
