(2R)-2-{2-[5-Fluoro-2-(methyloxy)phenyl]-2-methylpropyl}-2-(trifluoromethyl)oxirane (530 mg, 1.81 mmol) was added to acetonitrile (2.5 mL), followed by the addition of methyl 3-(4-amino-6-methyl-1H-indazol-1-yl)benzoate (590 mg, 2.1 mmol) and yttrium trifluoromethanesulfonate (197 mg, 0.37 mmol) at room temperature under a nitrogen atmosphere. The resulting mixture was then heated to reflux (83° C.) overnight, then allowed to cool down to room temperature and diluted with ethyl acetate (7 mL). The mixture was washed successively with saturated sodium bicarbonate (10 mL) and water (10 mL), dried and concentrated. The residue was then purified by column chromatography (10% ethyl acetate in cyclohexane) to give, after concentration, the title compound (540 mg).
