Participants

Reaction Steps

35 ml of ether was cooled to -78° C. and 20 ml of a 1.6 M solution of n-butyllithium in hexane was added thereto. To the obtained mixture, 5 g of 4-bromopyridine dissolved in 30 ml of ether was added. Then 5 g of 1,4-cyclohexanedione monoethylene acetal dissolved in 30 ml of tetrahydrofuran was further added thereto. After the completion of the reaction, the reaction mixture was poured into a saturated aqueous solution of ammonium chloride and purified by extracting with chloroform to give 5 g of 4-hydroxy-4-(4-pyridyl)cyclohexanone
