実験手順
Following the procedure of Example 1 but using 0.506 g. of PGA1 0.250 ml. of triethylamine, 0.236 ml. of isobutylchloroformate, and 0.412 g. of p-hydroxybenzamide there is obtained a crude residue. This residue is subjected to silica gel chromatography, eluting with chloroform-acetonitrile (6:4). The residue obtained by concentration of selected fractions, 0.260 g., an oil, as the title compound, having RfO.5 (TLC on silica gel in chloroform-acetonitrile (3:2)).
