Methods for preparing an L-6-hydroxytryptophan (HTP) derivative and intermediates thereof are provided. The methods for preparing the various intermediates of the L-6-HTP derivative are provided, on the basis of which the L-6-HTP derivative could be obtained. Specifically, the L-6-HTP derivative is obtained by using a compound A6-0 with a structure shown in Formula 1 as a starting reaction raw material, and subjecting the compound A6-0 to triisopropylsilyl (TIPS) protection, coupling, carbon-boron bond oxidation, hydroxyl-targeted benzyl protection, TIPS protective group removal, tert-butoxycarbonyl (Boc) protective group removal, methyl ester hydrolysis, and amino-targeted 9-fluorenylmethoxycarbonyl (Fmoc) protection in sequence.
