Participants

Reaction Steps

2 g (5.12 mmol) of the ketone obtained in Example 8, in 20 ml of benzene, were treated with 0.5 ml of ethylene glycol and 10 mg of TsOH. The reaction mixture was heated at reflux for 24 hours and was then neutralized with a saturated sodium bicarbonate solution. After extraction with ethyl ether, the organic phase was washed with water, dried over magnesium sulfate, filtered and evaporated to yield, after chromatography on silica in a hexane/EtOAc (90/10) mixture and triturating in hexane, 910 mg (41%) of the expected compound, melting at 136°-137° C.
