Abstract
The invention comprises compounds of general formula <FORM:0980593/C2/1> wherein R is alkyl (1-7 C) and R1 is 1-hydroxyalkyl (1-8 C) and the broken lines radiating from the rings denote bonds to optional substituents and that within the ring denotes that the bond in the 1,2-position may be a single or double bond; and their salts: and their preparation by treating a compound of formula <FORM:0980593/C2/2> wherein R10 is alkyl (1-7 C), with ammonia or an alkyl-amine (1-7 C) to give a 3,4-dihydroquinazolone I which is optionally reduced to a 1,2,3,4-tetrahydro-compound; which first reaction may proceed via an intermediate of formula <FORM:0980593/C2/3> (in an example N-(2-hydroxy-propionyl)-anthranilic acid N-methyl amide is isolated and heated to yield the product I) or when the reaction is performed in the presence of an alkanol R2OH (1-7 C) via an initial alcoholysis product of formula <FORM:0980593/C2/4> (for example 4-chloro-N-(2-hydroxy-propionyl)-5-sulphamyl-anthranilic acid methyl ester, then reacted with ammonia or methylamine). Pharmaceutical preparations comprise compounds I or salts thereof with compatible pharmaceutical carriers. Tablets, capsules, solutions, suspensions and suppositories are mentioned for oral, parenteral and rectal administration. The compounds are useful as diuretics, bronchodilators and hypotensives. Specification 980,592 is referred to.
