The mixture is cooled and extracted in its ether, washed with water, saturated sodium chloride solution and dried (CNa2SO4). Evaporation of the solvent gives a solid, (33.2 g): m.p. 42°-46° C. is heated at 60°-65° C. for 18 hours The mixture is cooled extracted in its ether washed with water, saturated sodium chloride solution dried (CNa2SO4) Evaporation of the solvent gives a solid, (33.2 g)

実験手順: 4-(Methyloxy)-1H-indazol-3-amine (for a preparation see Intermediate 1) (490 mg, 3 mmol) and potassium hydroxide (185 mg, 3.30 mmol) were dissolved in DMSO (30 mL). The reaction was left to stir for 30 min, before 4-(bromomethyl)-2-fluoro-1-(methyloxy)benzene (657 mg, 3.00 mmol) was added to the reaction mixture and stirred for 1 h at room temperature under nitrogen. The reaction mixture was diluted with ethyl acetate (250 mL) and washed with water (2×250 mL) and brine (250 mL). The organic layer was dried over anhydrous magnesium sulphate and filtered before being evaporated in vacuo to afford a brown oil. The residue was loaded in dichloromethane on a silica 100 g cartridge and purified by chromatography on Flashmaster using a 0-100% ethyl acetate-dichloromethane over 40 min. The appropriate fractions were combined and evaporated in vacuo and the residue re-purified by chromatography on silica 70 g using a 0-50% ethyl acetate-dichloromethane over 40 min. The appropriate fractions were combined and evaporated in vacuo to give the title compound (432 mg, 48%) as an off-white solid. LCMS (System A) RT=0.96 min, ES+ve m/z 302 (M+H)+.
