Procedure
246 mg of a mixture of methyl 5-chloro-2-methoxy-2-(4-methoxyphenyl)valerate with methyl methoxy-(4-methoxyphenyl)acetate was obtained from methyl hydroxy-(4-methoxyphenyl)acetate (724 mg) and 1-chloro-3-iodopropane (0.56 ml) by the same method as in Examples 85 and 86. Then, the ester mixture was hydrolyzed and amidated with tert-butyl carbazate according to the method in Examples 85 and 86 to obtain 32 mg of tert-butyl N′-[5-chloro-2-methoxy-2-(4-methoxyphenyl)pentanoyl]hydrazinecarboxylate and 122 mg of tert-butyl N′-[2-methoxy-2-(4-methoxyphenyl)acetyl]hydrazinecarboxylate.
