실험 절차
In a manner similar to Example 3, 2.2 g (10 mmol) of 4-(3-methoxy-4-trimethylsilyloxyphenyl)butan-2-one was treated with 10 mmol of lithium diisopropylamine, followed by 3 g (12 mmol) of 3-(4-benzyloxyphenyl)propan-1-al. Purification of reaction mixture by dry column chromatography (silica gel, hexane: ethyl acetate, 2:1) gave 0.5 g of the desired product as a pale yellow oil. MS(EI):434.
