Related Products of 137049-00-4, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 137049-00-4 name is 1-Methyl-1H-imidazole-4-sulfonyl chloride, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
0.07 g (0.21 mmol) of (R,3r)-3-((7S,8R)-7-(azetidin-1-yl)-8-benzyl-5,6,7,8-tetrahydronaphthalen-2-yl)cyclobutanamine were dissolved in dichloromethane, 0.05 g (0.41 mmol) dimethylaminopyridine were added, followed by 0.04 g (0.21 mmol) of 1-methyl-1H-imidazole-4-sulfonyl chloride. The mixture was stirred at room temperature overnight. The reaction mixture was evaporated and the residue was partitioned between ethyl acetate and aqueous bicarbonate solution. The aqueous phase was discarded and the organic phase was washed again with aqueous bicarbonate solution, then twice with aqueous ammoniumchloride solution (10%). The organic phase was dried over MgSO4 and evaporated to dryness. The desired product was obtained as a light brown resin (0.01 g, 0.01 mmol, 7%). ESI-MS [M+H+]=491 Calculated for C28H34N4O2S=490.
