Abstract
Procedure for obtaining new derivatives of nitrogen heterocycles, of the general formula: *** see image 01 where r can be: *** see image 02 yrºcan be *** see image 03 characterized this procedure because it consists of four stages: in the first, the acetyl derivative of the heterocycle is reacted with bromine, obtaining the bromoacetyl derivative. In the second, the reaction of this bromoacetyl derivative with an amine produces the corresponding amino ketone. In the third, this aminoacetone is reduced to aminoalcohol, obtaining this compound in free base form. In the fourth the free base is treated with an organic or inorganic acid obtaining the corresponding pharmacologically active salt. (Machine-translation by Google Translate, not legally binding)
