Potassium Carbonate → HCID 55297108, compound

Participants

Reaction Steps

Potassium carbonate (0.33 g) was added to a methanol (10 mL) solution of 1-{4-[(trimethylsilyl)ethynyl]phenyl}cyclopropylamine (0.37 g) as obtained in Example 21-(2), and the mixture was stirred for 1 hour at room temperature. After the potassium carbonate was filtered out and washed with chloroform, the solvent was distilled off under reduced pressure. The resulting residue was purified by OH type silica gel chromatography (gradient elution with hexane/AcOEt=70/30→30/70) to obtain 1-(4-ethynylphenyl)cyclopropylamine (Compound 404, yellow solid) (0.19 g, 76%).
