実験手順

Prepared from glutaric anhydride and starting compound A2 as described for compound 1. After evaporating the pyridine, the residue is partitioned between ethyl acetate and 1N hydrochloric acid. The ethyl acetate solution is dried over magnesium sulfate and evaporated. Crystallisation from diethyl ether. M. p. 133-135° C.
