Preparation method of theophylline sodium salt

The invention relates to the technical field of pharmaceutical chemicals, and particularly discloses a preparation method of theophylline sodium salt. The preparation method of theophylline sodium salt comprises the following process steps: mixing cyanoacetic acid and acetic anhydride for reaction to obtain mixed anhydride, and performing a condensation reaction on the mixed anhydride and 1,3-dimethylurea to obtain 1,3-dimethyl cyanoacetylurea; sequentially carrying out cyclization, nitrosation, hydrogenation and acylation on the 1,3-dimethyl cyanoacetylurea to obtain 1,3-dimethyl-4-amino-5-formylamino uracil; subjecting the 1,3-dimethyl-4-amino-5-formylamino uracil to ring closing to obtain the theophylline sodium salt. According to the preparation method, the reaction conditions are mildand easy to control, the product yield is high, byproducts are few, strong ammonia gas smell is avoided, the cost is low, and generated pollution wastes are few.
