The invention discloses a synthesis method of tri(diethylamino) tert-butyl amide tantalum, wherein the synthesis method comprises the following steps: 1) carrying out a mixed reaction of tantalum pentachloride and alkane, adding tert-butylamine, carrying out a reaction, then adding pyridine, carrying out a reaction, and thus obtaining a tantalum complex suspension after the reaction is completed; 2) adding diethylamine into an n-butyllithium.alkane CnH2n+2 solution, then adding the tantalum complex suspension of the step 1), and carrying out a reaction; and 3) removing a by-product lithium chloride of the liquid obtained from the reaction by a solid-liquid separator, transferring the obtained solution to a distiller, firstly, distilling off a CnH2n+2 alkane solvent with reduced pressure, and then distilling off the product tri(diethylamino)tert-butyl amide tantalum with reduced pressure. The synthesis method solves the problems of troublesome operation, low yield, low purity and high cost in the synthesis operation process of tri(diethylamino)tert-butyl amide tantalum.
