Reaction Steps

A solution of LAH in THF (1M, 0.25 mL, 0.25 mmol) was added to a solution of 1-(2-(N,N-diethylamino)ethyl)-6-(N-Boc-tetrahydro-4-pyridinyl)-1H-indazole (10.2 mg, 0.025 mmol) in THF (0.5 mL) at room temperature under argon and the resulting solution was refluxed for 2 h. After cooling to room temperature, the reaction was quenched using sodium sulfate decahydrate solid and the resulting solid was removed by filtration, extracting the product into ethyl acetate. The solvent was removed in vacuo and purification using an SPE (solid phase extraction) cartridge containing 1 g of silica gel by eluting with 0-10% 2M methanolic ammonia in dichloromethane yielded 1-(2-(N,N-diethylamino)ethyl)-6-(N-methyltetrahydro4-pyridinyl)-1H-indazole (5.9 mg, 74%).
