Potassium Hydroxide → HCID 23339948, compound

Participants

Reaction Steps

In a 100-mL three-necked flask equipped with a condenser and a stirrer, 2.92 g of potassium hydroxide and 20 mL of methanol were weighed and added, and 10.0 g of N-benzyl-N-methylpiperidinium chloride dissolved in 23 mL of methanol was added thereto dropwise over 10 minutes. At room temperature, the mixture was stirred for 1 hour, and precipitated potassium chloride was filtrated off. To the resultant filtrate, 0.44 g of silver oxide was added, and stirred for 1 hour at room temperature. Precipitated silver chloride and unreacted silver oxide were filtrated out, thereby obtaining 43.6 g of 20% solution of N-benzyl-N-methylpiperidinium hydroxide. The solution was confirmed to be the desired substance by NMR spectrum, MS spectrum and IR spectrum thereof.
