Paragraph 0057-0062, (2020/06/02)
The invention relates to the technical field of organic synthesis, and provides a preparation method of methoxy-substituted methyl-1H-indole-2-carboxylate. The preparation method comprises the following steps: mixing methoxy-substituted methyl(Z)-2-azido-3-phenyl acrylate, a ruthenium catalyst and tetrahydrofuran, and carrying out a cyclization reaction to obtain the methoxy-substituted methyl-1H-indole-2-carboxylate. According to the preparation method provided by the invention, the ruthenium catalyst is adopted for catalysis, and the methoxy-substituted methyl-1H-indole-2-carboxylate can beprepared without using high-toxicity toluene and high-toxicity xylene as solvents. The preparation method provided by the invention is relatively low in toxicity and relatively high in safety coefficient; and the yield of a product, namely the methoxy-substituted methyl-1H-indole-2-carboxylate purified by the method provided by the invention is relatively high and is 93% or above.
