The invention relates to the technical field of cyclophosphamide, in particular to a synthetic method of cyclophosphamide. The defects of low yield and high cost existing in the prior art are solved. The synthetic method includes the following methods: S1: simultaneously adding 3-aminopropanol and triethylamine into a phosphorus oxychloride solution and obtaining 2-chlorotetrahydro-2H-1,3,2-oxynitrogen phosphorus heterocyclohexene-2-oxide through mixing; S2: reacting 2-chlorotetrahydro-2H-1,3,2-oxynitrogen phosphorus heterocyclohexene-2-oxide with 2-chloroethylamine hydrochloride to obtain 2-[(2-chlormethine)amidogen]tetrahydrogen-2H-1,3,2-oxynitrogen phosphorus heterocyclohexene-2-oxide; simultaneously adding 3-aminopropanol and triethylamine into the phosphorus oxychloride solution, reversing an original preparation process, improving yield; and adding sodium borohydride/concentrated sulfuric acid into 3-(2-chloracetyl group)-2-[(2-chlormethine)amidogen]tetrahydrogen-2H-1,3,2-oxynitrogen phosphorus heterocyclohexene-2-oxide. Thus, yield value of the step is improved and the total yield is further improved.
