| titleOfInvention | A PROCEDURE FOR OBTAINING 4-OXO-2-2 (B-AMINOALCOHIL) -3,4-DIHYDRO- (BENZO-1,3-OXAZINES) OR ITS SALTS |
| abstract | A process for the preparation of 4-oxo-2- (B-amino-alkyl) -3,4-dihydro- (benzo-1,3-oxazines) or their salts, of the form: ** (See formula) ** wherein R1 represents a primary NH2 amino group or a monoalkohilized secondary NH (alkyl) amino group with a lower alkyl or N-alkyl (tertiary) amino group dialkylized with two lower alkyl, n the number 1 or 2, and R2 a hydrogen atom, a halogen or an amino group, characterized by mixing acrolein in ethyl solution with a molar amount of ammonia in gaseous form and in molar quantities, or with the corresponding secondary or tertiary amine, after which they are added to this solution molar quantities of salicylamide, optionally substituted, and the whole reaction mixture is treated with hydrochloric acid, the resulting hydrochloride being optionally converted to the free base.
