Abstract
5 : 5 disubstituted 2 : 4 diketotetrahydrooxazoles of the formula <FORM:0159153/2/1> where R and R1 are alkyl radicals or phenyl or its homologues are obtained by the interaction of disubstituted hydroxyacetamides and a chloroformic ester in the presence of a neutral solvent and alkali carbonate. Products are specified, according to examples, from ethylphenylhydroxyacetamide or methylphenylhydroxyacetamide and ethyl chloroformate in toluene or carbon tetrachloride solution and in the presence of potassium carbonate. The compounds have hypnotic, sedative, and narcotic properties. According to the Specification as open to inspection under Sect. 91 (3) (a), R and R1 may be radicals of the aliphatic or aromatic series. This subject-matter does not appear in the Specification as accepted.
