Abstract

Alkyl- or aryl- D 2, 3 - cyclopentenylbarbituric acids are prepared by condensing an alkyl- or aryl-D 2, 3-cyclopentenylmalonic acid ethyl ester with urea in the presence of alcohol and sodium ethylate, distilling off the alcohol progressively in an open vessel and heating the product to about 115 DEG C. The preparation of C : C-n-propyl-, isopropyl-, and n-butyl- D 2, 3-cyclopentenylbarbituric acids is described. The Specification as open to inspection under Sect. 91 (3) (a) describes also the preparation of the same compounds by treating the sodium compound of D 2, 3-cyclopentenylbarbituric acid with an alkyl or aryl halide and includes an example of the production of C : C-b -bromallyl-D 2, 3-cyclopentenylbarbituric acid by interaction of D 2, 3- cyclopentenylbarbituric acid dissolved in caustic soda with b -bromallyl bromide. This subject-matter does not appear in the Specification as accepted.
