실험 절차

The operation is carried out as in Example 1 Stages A, B and C but using 390 mg of 4-(3-hydroxyphenyl)-2-butanone and 818 g of ethyl 4-bromo-2-[[(phenylmethoxy)carbonyl]amino]butanoate (Stage A) then, during Stage B, 380 mg of 4,5-dihydro-1H-imidazol-2-yl-hydrazine hydrobromide. The saponification stage is carried out in the presence of soda in methanol. 110 mg of expected product is obtained in the form of an E/Z mixture 45/55.
