実験手順
Subsequently, the same procedure as in Reference Example 4 was repeated except that the ethyl 1-[N-(3,4-methylenedioxyphenylcarbonyl)amino]cyclohexanecarboxylate was replaced by 1.0 g (2.5 mmol) of phenylmethyl 1-[N-(4-methoxybenzenesulfonyl)amino]cyclohexanecarboxylate, whereby 450 mg of the captioned 1-[N-(4-methoxybenzenesulfonyl)amino]cyclohexanecarboxylic acid was obtained in a yield of 26%.
