Related Products of 137049-00-4, A common heterocyclic compound, 137049-00-4, name is 1-Methyl-1H-imidazole-4-sulfonyl chloride, molecular formula is C4H5ClN2O2S, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
To a solution of tert-butyl (6-(3-((6-amino-,3-dimethyl-2-oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)oxy)-5-propoxyphenoxy)hexyl)carbamate (67 mg, 0.12 mmol) in DCM (2 ml) were added 1-methyl-1H-imidazole-4-sulfonyl chloride (46 mg, 0.26 mmol) and pyridine (100 muL, 1.24 mmol), the sulfonyl chloride was not fully soluble, so dioxanes (2 mL) was added and the resulting mixture was stirred at 60 C. for 21 h. The resulting suspension was concentrated, then purified by silica-gel chromatography (1:5-1:1 EtOAc/hexanes then 100% EtOAc) and dried to give tert-butyl (6-(3-((1,3-dimethyl-6-(1-methyl-1H-imidazole-4-sulfonamido)-2-oxo-2,3-dihydro-1H-benzo[d]imidazol-5-yl)oxy)-5-propoxyphenoxy)hexyl)carbamate as a red-colored amorphous solid (58 mg, 68%).

The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
