Procedure

Under argon gas atmosphere, to a solution of cis-[2-(2-methyl-2H-indazol-4-yl)cyclopropyl]methanol (130 mg, 0.643 mmol) in tetrahydrofuran (6.5 mL) were added a solution (40%, 0.351 mL, 0.771 mmol) of diethyl azodicarboxylate in toluene, triphenylphosphine (219 mg, 0.835 mmol) and phthalimide (123 mg, 0.836 mmol), and the mixture was stirred at room temperature for 5 hr. To the reaction mixture was added a solution (40%, 0.176 mL, 0.386 mmol) of diethyl azodicarboxylate in toluene, triphenylphosphine (110 mg, 0.419 mmol) and phthalimide (61.5 mg, 0.418 mmol) were added, and the mixture was stirred at room temperature for 30 min. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=20/80→50/50) to give the title compound as a crudely purified product.
