1H-Pyrazole-4-sulfonylchloride,1-methyl-(9CI) Use and Manufacturing
Add 1 -methyl- lη-pyrazole (100 g, 1.18 mol) dropwise to chlorosulfonic acid (325 mL, 4.84 mol) stirring at 0 General procedure: To a solution of methyl 2-amino-4-fluorobenzoate (1.64 g, 9.71 mmol) and methanesulfonyl chloride (5.28 mL, 115 mmol) in dichloromethane (100 mL) was added pyridine (7.86 mL, 97.1 mmol). The solution was stirred at room temperature for 18 hours. The reaction was quenched with 1N HCl and was stirred for 5 minutes. The mixture was extracted with DCM (3×). The combined organic layers were washed with brine, dried over anhydrous MgSO4, filtered and concentrated. The crude product was purified by silica gel chromatography to afford methyl 4-fluoro-2-(methylsulfonamido)benzoate.In the 0 C, the 6-amino-2-(difluoromethyl)-7-methylquinolin-4-yl acetate (0.21 g, 0.8 mmol) and pyridine (10 ml) are added to the 50 ml single-port in the bottle, and then the Example 272 N-(1-((3R, 3aS, 9bS)-9b-((4-fluorophenyl)sulfonyl)-7-(perfluoropropan-2-yl)-2, 3, 3a, 4, 5, 9b-hexahydro-1H-cyclopenta[a]naphthalen-3-yl)ethyl)-1-methyl-1H-pyrazole-4-sulfonamide A stirred solution of a single diastereomer of 1-((3R, 3aS, 9bS)-9b-((4-fluorophenyl)sulfonyl)-7-(perfluoropropan-2-yl)-2, 3, 3a, 4, 5, 9b-hexahydro-1H-cyclopenta[a]naphthalen-3-yl)ethan-1-amine (Example 225; 8 mg, 0.015 mmol) in DMSO (0.3 mL) was treated with
