Abstract
255,811. Deutsche Gold-und Silber- Scheideanstalt vorm. Roessler. July 22, 1925, [Convention date]. 2-Hydrazino-5-nitropyridine is prepared by treating a 2-halogen-5-nitropyridine with hydrazinc hydrate. Preferably the reaction is effected with cooling in the presence of a solvent such as water. According to the examples, 2-hydrazino- 5-nitropyridine is obtained by (1) adding powdered 2-chlor-5-nitropyridine to hydrazine hydrate, and (2) suffusing 2-chloro-5-nitropyridine with a 50 per cent aqueous solution of hydrazine. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the use of alcohol as a solvent. This subject-matter does not appear in the Specification as accepted. 2-Bromo. and 2-iodo-5-nitropyridine are prepared by diazotizing 2-amino-5-nitropyridine in the presence of concentrated hydrobromic and hydriodic acid respectively.
