E. The 2,3,5-triphenylformamidine (IV-1) solid obtained in Step D was mixed with 300 mL of dichloromethane and 300 mL of water. After the solid was completely dissolved, N-chlorosuccinimide (0.11 mol, 14.7 g) was added and the reaction was carried out with stirring at 0 °C for 5 h. F. The reaction mixture from Step E was allowed to partition and the upper aqueous phase was separated. The organic phase was distilled under reduced pressure to remove the solvent to give the crude product 2,3,5-triphenyltetrazole (V-1). The crude product was purified by recrystallization with chloroform to give 30.2 g of pure product (yield: 90%).

1.E; 1.F Example 1 A method for preparing 2,3,5-triphenyltetrazole compound V-3,
E. Mixing the solid 2,3,5-triphenylformamidine IV-1 obtained in step D with 300 mL of dichloromethane and 300 mL of waterAfter the solvent was dissolved, N-chlorosuccinimide (0.11 mol, 14.7 g) was added, and the reaction was carried out at 0 ° C for 5 h;F. The mixed solution in step E is allowed to stand for stratification, the upper layer (aqueous solution) is taken out, and the solvent is distilled off to obtain 2, 3, 5-triphenyltetrazole compound V-1 was purified by recrystallization from chloroform to give 30.2 g (yield: 90%).
