Acetic Acid → 1-(4-(4-((Cyclobutylamino)methyl)phenyl)piperazin-1-yl)ethanone

Participants

Reaction Steps

To a solution of 4-(4-acetylpiperazin-1-yl)benzaldehyde (150 mg, 0.64 mmol) and cyclobutylamine (75 mg, 0.77 mmol) in dichloroethane (1.5 mL) was added sodium triacetoxyborohydride (216 mg, 0.96 mmol), followed by acetic acid (0.055 mL, 0.96 mmol) and the reaction was stirred at ambient temperature for 16 hours. The reaction was then quenched with 1 N aqueous NaOH, diluted with dichloromethane and the dichloromethane layer was isolated with a phase-separator cartridge and concentrated to give 1-(4-(4-((cyclobutylamino)methyl)phenyl)piperazin-1-yl)ethanone (185 mg). The product was used without purification. LCMS (m/z) ES+ 288 [M+1]+.
