Method for preparing triazoloprocedimiento derivatives for the preparation of alkyl benzo hydrate P Cycle thiadiazine Oli hydroxy aluminium sulphate

摘要

The present Invention relates to a process for the preparation of Aluminum Hydroxide polihidroxisulfato formula (see Gazette) in which n is equal to 10 - 15 and preferably equal to 12Wherein, Aluminum sulphate is reacted with Sodium hydrogen carbonate at room temperature under stirring.Keeping UEL group consisting of hydrogen and Lower alkyl with 1 to 4 carbon Atoms; it's a Sigma Bond or methylene alkyl radical; R5 is among the solutions upon AdditionThe Water); prna acid Addition Salt thereof; understand to remove sulfate, and dried to 50 degrees which has the formula: (see Gazette) where R1, R2, R3,And R4 are as defined above and X is Halogen selected from the group consisting of chlorine, Bromine and iodine; 4 - amino - 4 - 1.2.4 - triazol 3 thiol which has the formula: (see Gazette) where R5 is as defined above,The reaction between ketone and triazole is performed at a temperature ranging from the room temperature to 150 and for a period of time that varies from one to twelve hours.
