Abstract
8-Aminoquinaldine and its nuclear substitution products are obtained by heating 8-hydroxyquinaldine or its ethers or esters, or the substitution products of any of these compounds, with ammonia (or a reagent which yields ammonia) at about 150-220 DEG C. in the presence of a sulphite or bisulphite or in the absence of oxygen or a gas containing oxygen. In the examples: (1) 8-hydroxyquinaldine is heated with ammonia and aqueous sodium bisulphite solution to yield 8-aminoquinaldine; (2) 8 - methoxyquinaldine and 8 - acetoxyquinaldine are treated as in example 1 to yield 8-aminoquinaldine; (3) 8-hydroxyquinaldine is heated with urea in an atmosphere of nitrogen; 8 - aminoquinaldine is again obtained; (4) 8 - hydroxy - 5 - methylquinaldine is treated as in example 1 to yield 8-amino-5-methylquinaldine. Specification 395,063 is referred to.
