Procedure
To a solution of 116 mg (0.305 mmol) of 3-[2-benzyl-7-(trifluoromethyl)-2H-indazol-3-yl]benzaldehyde (compound of Formula (I)), prepared in a same way as Example 1, in 2 ml of methanol, 23 mg (0.71 mmol) of NaBH4 was added at 0° C. The reaction mixture was stirred at this temperature for 1 hr. Saturated NH4Cl-solution and dichloromethane were added, and the phases were separated. The product was obtained after flash chromatographic purification using dichloromethane as eluant. Yield: 111 mg.
