Novel [2-[(aminopyridinyl)amino]phenyl]arylmethanones and their thioxomethyl, ketal or thioketal analogs of the formula: ##STR1## wherein; R is selected from the group consisting of hydrogen, loweralkyl, --alk.sup.1 --halo, --alk.sup.1 --NR.sup.1 --NR.sup.1 R.sup.2 or --alk.sup.1 --N.dbd.CH--OC.sub.2 H.sub.5 ; R.sup.1 and R.sup.2 are selected from the group consisting of hydrogen, loweralkyl, --C(O)O-loweralkyl or R.sup.1 and R.sup.2 taken together with the adjacent nitrogen atom may form a heterocyclic residue selected from the group consisting of 1-piperidinyl, 1-phthalimido, 1-pyrrolidinyl, 4-morpholinyl, 1-piperazinyl and 4-substituted-1-piperazinyl; B is selected from carbonyl, thioxomethyl, ketal or thioketal; Ar is selected from the group consisting of 2, 3 and 4-pyridinyl, 2 or 3-thienyl, phenyl or phenyl substituted by 1 to 3 radicals selected from halo, loweralkyl, loweralkoxy, trifluoromethyl or nitro and may be the same of different; alk.sup.1 is a straight or branched hydrocarbon chain containing 1-8 carbon atoms; Z is selected from the group consisting of hydrogen, halogen, loweralkyl, loweralkoxy, hydroxy or nitro; Y is selected from the group consisting of hydrogen or 1-2 radicals selected from loweralkyl, loweralkoxy or hydroxy and may be the same of different, and the acid addition salts thereof. These compounds are intermediates in the preparation of novel aryl substituted pyrido[1,4]benzodiazepines having antidepression activity. Some of these intermediates are useful in treating depression.
