実験手順: The title compound was prepared from 2-(5-hydroxy-1H-pyrazol-1-yl)pyridine-4-carbonitrile and (4-fluoro-2-methylphenyl)methanol according to the procedure for the preparation of Example 39, part C. 1H NMR (400 MHz, CDCl3): δ 2.38 (3H, s), 5.17 (2H, s), 5.78 (1H, d, J=1.6 Hz), 6.89-6.95 (2H, m), 7.34-7.39 (2H, m), 7.58 (1H, d, J=2.4 Hz), 7.98 (1H, s), 8.67 (1H, d, J=5.2 Hz). [M+H] Calc'd for C17H13FN4O, 309; Found, 309.

実験手順: (4-Fluoro-2-methylphenyl)methanol (11.5 g, 82 mmol) was dissolved in CH2Cl2 (100 mL). The mixture was cooled to 0° C. before adding SOCl2 (10.7 g, 90 mmol), then stirred for 30 min at 0° C. and then at room temperature for 1.5 h. The solvent and excess of SOCl2 were removed by evaporation followed by the addition of CH2Cl2. The solvent and remaining traces of SOCl2 were evaporated once more. There was obtained 13.0 g (100%) of 1-(chloromethyl)-4-fluoro-2-methylbenzene as an oil. 1H NMR (300 MHz, CDCl3): 2.4 (s, 3H), 4.6 (s, 2H), 6.8-7.0 (m, 2H), 7.3 (m, 1H). at room temperature for 1.5 h The solvent and excess of SOCl2 were removed by evaporation followed by the addition of CH2Cl2 were evaporated once more

実験手順: 4-Fluoro-2-methylbenzoate (15.3 g, 91 mmol) was dissolved in THF under a stream of nitrogen. The mixture was cooled to 0° C. while adding LiAlH4 (4.4 g, 110 mmol) in small portions and then stirred at room temperature for 1 h. Water (4.4 mL), aqueous 15% NaOH (4.4 mL) and then more water (13.2 mL) were added dropwise in the given order while cooling to 0° C. The mixture was stirred for 2 h and then the solid material was filtered off. The solvent was removed by evaporation and there was obtained 11.5 g (90%) of (4-fluoro-2-methylphenyl)methanol as an oil. 1H NMR (300 MHz, CDCl3): 2.4 (s, 3H), 4.6 (s, 2H), 6.8-6.9 (m, 2H), 7.3 (t, 1H). while cooling to 0° C The mixture was stirred for 2 h the solid material was filtered off The solvent was removed by evaporation

実験手順: To 14.3 parts of thionyl chloride is added dropwise a solution of 14 parts of 4-fluoro-2-methylbenzenemethanol and 0.9 parts of N,N-dimethylformamide in 45 parts of methylbenzene while cooling in ice-water. Then there are added 135 parts of methylbenzene and stirring is continued for 1 hour at room temperature. The reaction mixture is evaporated, yielding 17 parts (100%) of 1-(chloromethyl)-4-fluoro-2-methylbenzene as a residue. The reaction mixture is evaporated
