New compounds of the formula ##STR1## in which R.sub.1 and R.sub.2 =H or alkyl and (a) R=CN or alkylcarbonyl, or (b) R=CON(R.sub.3)R.sub.4, in which R.sub.3 =H and R.sub.4 =NH.sub.2, alkylamino, dialkylamino, phenylamino or diphenylamino; or R.sub.3 and R.sub.4 =H, alkyl (1 to 5 C) or substituted phenyl; or R.sub.3 =H and R.sub.4 =pyridyl or alkyl (1 to 5 C) substituted by COOH, NH.sub.2, alkylamino, dialkylamino, morpholino, piperidino, pyrrolidin-1-yl, piperazin-1-yl (optionally substituted by alkyl, pyridyl or optionally substituted phenyl or benzyl), optionally substituted phenyl, pyridyl or imidazolyl; or R.sub.3 and R.sub.4 form an imidazolyl radical or a 5-membered or 6-membered heterocycle which can contain an oxygen, sulphur or nitrogen atom and which is optionally substituted by alkyl, alkoxycarbonyl, hydroxyalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, pyridyl, pyrimidinyl, pyrazinyl, optionally substituted phenyl or optionally substituted benzyl; or (c) R=--C(.dbd.NOH)NH.sub.2 or --C[.dbd.NN(R'R")NH.sub.2 ], in which R' and R"=alkyl, the said alkyl radicals and alkyl portions being straight-chain or branched-chain and, unless mentioned otherwise, containing 1 to 4 carbon atoms, and the substituted phenyl and benzyl radicals carrying a halogen atom or an alkyl, alkoxy, alkylthio, trifluoromethyl or dialkylamino radical, and their tautomeric forms, addition salts with acids and the metals salts and the addition salts with nitrogen bases, are useful anti-allergic and anti-inflammatory agents. A variety of methods of making them are described.
