実験手順
The title compound (30 mg) was prepared in two steps from crude 2-(5-amino-3-methyl-1H-pyrazol-4-yl)-5-fluorobenzothiazole-6-sulfonic acid, which had been derived from the chlorosulfonation of 90 mg of 4-(5-fluorobenzothiazol-2-yl)-5-methyl-2H-pyrazol-3-ylamine, and a solution of excess ammonia dissolved in ethanol. MS (m/z, ES+): 328.0 (M+1,100%). Yield=25%.
