Procedure

101.5 mg (0.13 mmol) of the compound from example 29A and 23.0 mg (0.17 mmol) of trans-2-heptenoic acid are introduced under argon into anhydrous dimethylformamide (2 ml) at 0° C. and then 65.0 mg (0.17 mmol) of HATU and 0.025 ml (0.14 mmol) of ethyldiisopropylamine are added. After 30 min, a further 0.05 ml (0.29 mmol) of ethyldiisopropylamine are added to the reaction mixture. The reaction mixture is stirred overnight with slow warming to RT. The reaction solution is subjected directly to an RP-HPLC using acetonitrile/water as eluent. In the course of this, 63 mg (62% of th.) of a colorless solid are obtained.
