Pyridine → 3-Methylcarbonyloxyquinoline

Participants

Reaction Steps

1.35 ml of acetyl chloride are added dropwise to a mixture of 2.5g of 3-hydroxyquinoline (prepared by the method described by Mills and Watson in J.Chem. Soc., 97, 753 (1910)), 8.6 ml of pyridine and 50 ml of methylene chloride, while cooling with ice. After the reaction mixture has been stirred at room temperature for 10 minutes, 50 ml of water are added. Customary working up and purification of the crude product by FC over 50 g of silica gel (mobile phase C) gives 3-methylcarbonyloxyquinoline: Rf (A)=0.55; IR (CH2Cl2): 1770(s) cm-1.
