The synthetic route is as follows.
Step A: 6-chloro-5-iodo-2-(methylsulfonyl)-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-benzo[d]imidazole (0768) To a suspension of 6-chloro-5-iodo-2-(methylsulfonyl)-1H-benzo[d]imidazole (5.042 g, 14.14 mmol) in DCM (100 mL) at 0 C. was added TEA (2.96 mL, 21.21 mmol), and SEM-C1 (2.76 mL, 15.55 mmol) dropwise. The resulting solution was stirred from 0 C. for 1 hr. The reaction mixture was partitioned between water (200 mL) and DCM (100 mL), the aqueous phase was extracted with DCM (200 mL), and the combined organic phase was dried over anhydrous Na2SO4, concentrated and the residue was purified on silica gel column using EtOAc/hexane as eluting solvents to give the title compound. LC/MS: (M+1)+: 487.17.
The chemical industry reduces the impact on the environment during synthesis 5-Chloro-6-iodo-2-(methylsulfonyl)-1H-benzo[d]imidazole. I believe this compound will play a more active role in future production and life.
