4-Benzylpiperidine → HCID 57597291, compound

Participants

Reaction Steps

A mixture of 3-(5H-pyrrolo[3,2-d]pyrimidin-4-ylamino)benzoic acid (153 mg), 4-benzylpiperidine (158 mg), 1-[3-(dimethylamino)propyl]-3-ethylcarbodiimide hydrochloride (173 mg), 1-hydroxybenzotriazole (138 mg) and N,N-dimethylformamide (10 mL) was stirred at room temperature for 3 hrs. The reaction mixture was concentrated under reduced pressure, water was added and extracted with ethyl acetate containing tetrahydrofuran. The extract washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the obtained residue was purified by silica gel column chromatography (eluent, methanol:ethyl acetate=0:100→20:80). The obtained product was dissolved in ethyl acetate containing methanol and tetrahydrofuran, washed with aqueous sodium hydrogen carbonate solution and saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and diisopropyl ether was added to the obtained residue. The precipitate was collected by filtration to give the title compound (201 mg) as a pale-brown powder.
