Method for preparing pharmaceutical intermediate of tryptophan derivative

The synthesis method comprises the following steps: L - tryptophan derivatives are taken as starting materials, and esterification is carried out in sequence. The amidation, Boc protection, hydrolysis, amidation or sequential esterification, amidation, Boc protection, hydrogenation, hydrolysis, amidation yields a target product, a tryptophan derivative pharmaceutical intermediate. The preparation method has the advantages of cheap and easily available raw materials, environment friendliness, less process three wastes, accords with the idea of green pharmacy, mild reaction conditions, simple process, simple and convenient operation, high yield and purity and easy amplification and production.
