実験手順

13.2 parts by weight of 1-carbobenzoxypiperidine-4-carboxylic acid are dissolved in 150 parts by volume of methylene chloride, 8 parts by volume of n-octanol and 0.7 part by weight of 4-pyrrolidinopyridine are added, and the mixture is cooled to 0 to 5° C. 12.0 parts by weight of dicyclohexylcarbodiimide are added, and the mixture is stirred at 5° C. for 2 hours and at room temperature for 4 hours. The mixture is left to stand overnight, the precipitated dicyclohexylurea is filtered off with suction (11.3 parts by weight), the solvent is stripped off in vacuo, the residue is stirred with diisopropyl ether in order to remove residual dicyclohexylurea and filtered, and the solvent is stripped off. 21 parts by weight of an oily residue are obtained. The residue is chromatographed on 1070 parts by weight of silica gel using CH2Cl2 /5% of methanol. 9.8 parts by weight of the compound (A) are obtained as an oil. ##STR42## 4-decyloxyphenoxy(4-benzoyl) chloroformate =(B)
