Procedure

In analogy to the procedure described in example 3, treatment of (rac)-2-{4-[(E)-3-(3,4-dichloro-phenyl)-acryloyl]-7-oxo-[1,4]diazepan-1-yl}-4-hydroxy-butyric acid methyl ester (with 50% of the lactone, 1-[(E)-3-(3,4-dichloro-phenyl)-acryloyl]-4-(2-oxo-tetrahydro-furan-3-yl)-[1,4]diazepan-5-one) (intermediate 6) in EtOH with piperidine for 1.5 days at 60° C. and 2 days at RT gave 43% of the titled compound as light yellow foam. MS: 482.2 (MH+, 2Cl).
