Sodium amide (15.6 g, 0.4 mol) was added portionwise to a solution of cyclohexanone (39.26 g, 1.46 mL, 0.4 mol) in 350 mL of anhydrous diethyl ether. The resulting suspension was heated under reflux for 3 h after which time benzyl chloride (46.8 g, 42.6 mL, 0.37 mol) was rapidly added. The mixture was heated under reflux for a further 5 h, then cooled and poured into cold water. The organics were washed once with a dilute HCI solution, a dilute sodium bicarbonate solution and finally with water. The organic layer was dried, filtered and the ether was removed to give 2-benzylcyclohexanone as an oil (28 g, 40%).
