1,207,249. Aniline derivatives. CIBA Ltd. 29 May, 1968 [29 May, 1967], No. 25848/68. Heading C2C. [Also in Division C4] Compounds of the formula where R 1 and R 2 represent H or alkyl or R 1 and R 2 are bound to the residues A 1 and A 2 respectively to form heterocyclic rings, R 3 and R 4 each represent an alkylene group, A 1 and A 2 each represent a phenylene residue in which the H atom and the secondary or tertiary amino group are in 1,4-position to each other and Z is a bifunctional bridging group which has no dyestuff characteristics and which contains at least one quaternated N atom are obtained by (1) reacting one mole of a ditertiary-amine with one mole of a monoamine containing an anion forming substituent; (2) reacting two moles of a di-tertiary-amine with one mole of a dibromo-alkane; or (3) reacting two moles of a monoamine containing an anion forming substituent with one mole of a mono- or di-amine. #,#<SP>1</SP> - Diacetoxy -γ,γ<SP>1</SP> - di - (N - phenyl - N - ethylamino)-tripropylamine is obtained by heating #,γ,#<SP>1</SP>,γ<SP>1</SP>-diepoxytripropylamine with N-ethylaniline in chlorobenzene to give #,#<SP>1</SP>- dihydroxy -γ,γ<SP>1</SP> - di - (N - phenyl - N - ethylamino) - tripropylamine and acetylating this compound with acetic anhydride. 2,6 - Bis - (N,N - bis - # - acetoxyethyl - 3 - aminoanilido) - pyridine is obtained by acetylating N,N-bis-#-hydroxyethyl-3-nitroaniline to give N,N-bis-#-acetoxyethyl-3-nitroaniline which is hydrogenated to give the corresponding amino compound and then reacted with pyridine-2,6-dicarboxylic acid chloride in chlorobenzene to give the required compound.
