Synthesis method for benzhydrylamine

The invention discloses a synthesis method for benzhydrylamine. The synthesis method comprises the following steps: adopting benzophenone and oxammonium hydrochloride as raw materials for reaction to obtain benzophenone oxime; reducing the benzophenone oxime into the benzhydrylamine under the action of ceraceous bacillus. The novel synthesis method that the method is mild in reaction conditions, simple to operate, high in reaction yield, free from contamination, and low in cost.
