実験手順

The title compound (280 mg) was prepared from crude 2-(5-amino-3-methyl-1H-pyrazol-4-yl)-4-fluorobenzothiazole-7-sulfonyl chloride, which had been derived from the chlorosulfonation of 320 mg of 4-(4-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=72%.
