Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
80 words
An arylaminopyridine compound of the formula: ##SPC14## or salt thereof wherein R represents hydrogen; Ar is phenyl or substituted phenyl bearing a substituent selected from the group consisting of chlorine, bromine, fluorine, nitro, cyano, alkyl of 1-4 carbon atoms and trifluoromethyl; X is selected from the group consisting of chlorine, bromine and fluorine; and n is 3 or 4; provided that when X is Cl, and n is 4, Ar is a substituted phenyl which bears 2 or 3 substituents.
Claim 2
Dependent Claim
