Reaction Steps
4.8 g (77 mmol) of ethanethiol was added to a solution containing 8.6 g (77 mmol) of potassium t-butoxide in DMSO (70 ml), under cooling with ice, and 8 g (35 mmol) of 4-fluoro-2-methyl-2H-indazole-3-sulfonamide was further added thereto. This mixture was stirred at 120° C. for 2 hours. After confirming the disappearance of the starting material by TLC, treatment was conducted in the same manner as in Preparation Example 6 to obtain 6.8 g (yield: 72.5%) of the desired product. Melting: 145°-147° C.
