Breene assists the amine and intermediate preparation method (by machine translation)
The invention discloses breene assists the amine and intermediate preparation method. If the compound of the present invention C breene assists the amine intermediates shown in preparation method comprises the following steps: under anhydrous conditions, in an organic solvent, in the presence of a tertiary amine, the compound B with the original acid ester compound for 70 – 80 C condensation under reaction, can be; wherein said original ester compound as the original b acid tri methyl ester, the original acetic acid triethyl and original benzoic acid methyl ester in one of three or more. Preparation method of this invention using a tertiary amine as catalyst condensation reaction, thereby greatly shortening the amino protection step of reaction time, reduces the reagent consumption, reduce the reaction temperature, and improves product yield and purity; and post-treatment process for use in the acid-base consumption is reduced, to reduce the product residue on ignition, the operation is simplified, is more suitable for industrial production.
