Paragraph 0051; 0052, (2019/11/13)
The invention provides a preparation method of 4-fluoro-5-hydroxy-2-methyl-1H-indole. The preparation method comprises the steps that 2-fluoro-3-halo-6-nitrotoluene is used as a raw material and subjected to a substitution reaction with alcohol to prepare 2-fluoro-3-GO substituent-6-nitrotoluene, then 2-fluoro-3-GO substituent-6-nitrotoluene is subjected to a condensation reaction with trimethyl orthoacetate or triethyl orthoacetate to obtain 1-(2-fluoro-3-GO substituent-6-nitrophenyl)-2-alkoxy propylene, and then 1-(2-fluoro-3-GO substituent-6-nitrophenyl)-2-alkoxy propylene is further subjected to a reduction-cyclization reaction to obtain 4-fluoro-5-hydroxy-2-methyl-1H-indole. The preparation method is safe and green, simple in operation, low in cost, high in selectivity and high in yield and purity of a final product.
