Reaction Steps

Sodium hydride (0.8 g., 0.033 mole) is suspended in a mixture of benzene (50 ml.) and dimethylformamide (50 ml.) and 3-phenyl-7-benzyloxy-2-dodecanone (12.1 g., 0.033 mole) is added dropwise. The resulting mixture is heated on the steam bath for 1 hour and then cooled to room temperature. Ethyl 7-bromoheptanoate (8.8 g., 0.037 mole) is added dropwise and the mixture is heated on the steam bath for 24 hours. The reaction mixture is cooled, poured into water (200 ml.) and the oily product taken up in ether and dried over sodium sulfate. The solvent is distilled in vacuo to leave 14 g. of ethyl 8-acetyl-8-phenyl-12-benzyloxyheptadecanoate as a yellow oil which is used in Step G without further purification.
