Abstract

" 3 of the nitrile 7 with sulfuric acid followed by water or methanol gave the amide 13, identical with that prepared by dimerization of 10. Although this amide 13 resisted further hydrolysis under mild conditions, it could be converted to the acid 12 by treatment with nitrous acid. The latter, with diazomethane, gave the tricyclic ester 11, identical with that prepared from 8. The tricyclic ester 11 could be converted to the amide 13 by reaction with ...
