To the above prepared N-(4-benzothiazol-2-yl-1H-pyrazol-3-yl)-formamide (0.50 g, 2.0 mmol) in 50 mL of anhydrous THF at 0° C. was added 0.50 g of lithium aluminum hydride. The reaction was stirred for 1 hr and then was quenched by the addition of saturated ammonium chloride solution. The solids were removed by filtration. The solvent was then evaporated and the crude product was purified by recrystallization from acetone to yield 280 mg (61%) of the title compound. MS (m/z, ES+): 231.1 (M+1, 100%).
