참여 물질

반응 단계

To a solution of [2-(ethoxycarbonyl)-1-benzothien-6-yl]acetic acid (100 mg, 0.38 mmol) and 4-methoxybenzohydrazide (63 mg, 0.38 mmol) in 2 mL DMF was added 3-{[(ethylimino)methylene]amino}-N,N-dimethylpropan-1-aminium chloride (91 mg, 0.47 mmol). The reaction was stirred at ambient temperature for 12 hours. The reaction mixture was loaded directly onto a reverse phase C18 column for purification to give the title compound as a white solid. LC/MS (EI): cal'd 413.1 (MH+), exp 413.1 (MH+).
