Versuchsvorschrift
The operation is carried out as in Example 1 Stages A, B and C but using 190 mg of 3-(4-hydroxyphenyl)-propanal and 530 mg of ethyl 4-bromo-2-[[(phenylmethoxy)carbonyl]amino]butanoate (Stage A) then, during Sage B, 92 mg of 4,5-dihydro-1H-imidazol-2-yl-hydrazine hydrobromide. 20 mg of expected product is obtained in the form of an E/Z mixture 90/10.
