Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
28 words
A compound of the formula (I); wherein R is a hydrogen atom or a methyl group; the hydrates or the pharmaceutical acceptable acid addition or alkali salts thereof.
Claim 2
Dependent Claim
28 words
A compound of the formula (I); wherein R is a hydrogen atom or a methyl group; the hydrates or the pharmaceutical acceptable acid addition or alkali salts thereof.
Claim 3
Dependent Claim
101 words
A process for the preparation of a compound of the formula (I) wherein R is a hydrogen atom or a methyl group; the hydrates or the paramaceutical acceptable acid addition or alkali salts thereof characterized b y condensing a compound of the formula (II); wherein R 1 is a hydrogen atom or a lower alkyl group and X is a halogen atom; with a secondary amine of the formula (III); wherein R is a hydrogen atom or a methyl group; however, when R 1 is a lower alkyl group, the condensed product may be saponified to the carboxylic acid specified above.
