Participants

Reaction Steps

N-[5-(3,5-Difluoro-benzyl)-1H-indazol-3-yl]-2-fluoro-5-formyl-benzamide (150 mg, 0.367 mmol) in THF (4 mL), under a nitrogen atmosphere, at room temperature was treated with N-methylpiperazine ((0.039 mL, 0.367 mmol) and then with acetic acid (0.024 mL, 0.422 mmol). After 0.5 hours sodium triacetoxyborohydride was added and the reaction was stirred over night. EtOAc (25 mL) and water (25 mL) were added, pH was adjusted to 11 with concentrated NH4OH. The organic layer was separated and the aqueous layer was extracted twice with EtOAc (2×10 mL). The combines organic extracts were dried over sodium sulphate, evaporated to dryness and purified over silica gel (Eluent:DCM: 7N NH3 in MeOH 96:4) affording 177 mg of title compound.
