| titleOfInvention | PROCEDURE FOR THE PREPARATION OF SUBSTITUTED QUINAZOLINE |
| abstract | The present invention relates to a process for the preparation of substituted quinazoline, of the formula: (SEE FIGURE) where X and Y are located at position 6, 7 or 8 and are the same or different and are selected from the group consisting of hydrogen, alkyl with 1 to 6 carbon atoms inclusive, alkoxy with 1 to 6 carbon atoms, inclusive, halogen; n is 1 or 2; or a physiologically acceptable acid addition salt, comprising reacting a 1,2-dihydro-2,2,4-trimethylquinoline of the formula: (SEE FIGURE) or one of its acid addition salts wherein X and Y have the above limitations, with an N-cyanoamine of the formula: (SEE FIGURE) where n is 1 or 2, in the presence of a solvent inert to the reagents and product, and solubilizes the reagents, and a catalytic amount of a strong mineral acid at an elevated temperature. |
