The invention discloses a process for synthesizing 1-benzhydrylazetidin-3-formaldehyde. The process includes the following specific steps: (1) under the action of an alkali, subjecting 1-benzhydrylazetidin-3-ol and phosphorous tribromide to reaction in a dried aprotic solvent to obtain 1-benzhydrylazetidin-3-bromo; (2) in a dried solvent, subjecting the 1-benzhydrylazetidin-3-bromine to reaction with magnesium chips to generate form Grignard reagent; subjecting the Grignard reagent to reaction with dried DMF (dimethyl formamide), carrying quenching reaction with ammonium chloride after reaction, and post-treating to obtain the target product 1-benzhydrylazetidin-3-formaldehyde. The process of the invention is stable to perform, high in yield, low in output of three wastes and low in production cost. The produced product has good quality.
