Abstract

The invention comprises compounds of the general formula <FORM:0822696/IV (a)/1> and acid addition salts thereof, wherein R1 stands for a saturated non-aromatic hydrocarbon group containing 2-7 carbon atoms and the broken line denotes that the methyl group is optional, and the preparation thereof by either condensing an acid of the formula <FORM:0822696/IV (a)/2> or a salt thereof with an organic base (in the presence of a carbodiimide) or a reactive derivative thereof with a substituted hydrazine of the formula R1-NH-NH2 or reacting a nicotinic acid hydrazide of the formula <FORM:0822696/IV (a)/3> with a carbonyl compound containing 2-7 carbon atoms, simultaneously or successively hydrogenating the resulting hydrazone and in either case, if desired, transforming the product (if a base) into an acid addition salt or (if an acid addition salt) into the base. It is further disclosed in the Specification that the hydrazone formed in the alternative process above may be reacted with a Grignard reagent and the product hydrolysed to form a hydrazine. N,N1 - Disubstituted - carbodiimides (e.g. N,N1-dicylohexylcarbodiimide) used in the condensation reaction may be prepared by treating an appropriately di-substituted-urea with p-toluenesulphochloride in piperidine.
