Reaction Steps

Sodium hydride (21 mg, 90 mmol) was slowly added into a solution of 6-acetyl-4,4-dimethyl-3,4-dihydro-1H-quinolin-2-one (Intermediate 5, 98 mg, 45 mmol) in 3 mL of DMF at 0° C. After stirring at 0° C. for 10 min, 1-iodo-n-hexane (29 mg, 135 mmol) was added to the reaction mixture and the ice-bath was removed. The reaction was allowed to stir for 2 h before quenching with ice water. The resulting solution was then extracted with ether (3×10 mL), washed with brine (1×10 mL), dried (MgSO4) and concentrated at reduced pressure. Purification by flash chromatography (75:25 hexane/ethyl acetate) yielded the title compound as a colorless oil (41.8 mg, 31% yield).
