Reaction Steps

A 0.5M solution of B-benzyl-9-BBN in tetrahydrofuran (1.8 ml) was added to a solution of tert-butyl {[3-bromo-1-(3-methoxypropyl)-1H-indazol-6-yl]methy}cyclopropylcarbamate (200 mg), potassium phosphate (290 mg), palladium acetate(II) (4 mg) and S-Phos (15 mg) in N,N-dimethylformamide (5 ml) under argon atmosphere and the mixture was stirred at 60° C. for 18 hours. Water was added to the reaction mixture under ice-cooling and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, dried over sodium sulfate and concentrated in vacuo. The resulted residue was purified with a silica gel column chromatography (eluting solvent: n-hexane to n-hexane/ethyl acetate=2/1) to give tert-butyl {[3-benzyl-1-(3-methoxypropyl)-1H-indazol-6-yl]methy}cyclopropylcarbamate (198 mg) as a colorless oil.
