Yield: 92.3%
Reaction Conditions:
in ethanol for 10 h;Reflux;
Steps:
1.1-3
116.2 g (0.520 mol) of synthesized in [Scheme 2], 43.7 g (0.520 mol) of cyclopentanone and 1162.0 ml of ethanol were added to a 2 L round bottom flask and refluxed for 10 hours. After the reaction was completed, the reaction solution was concentrated and then column chromatography was used to obtain 120.0 g (yield 92.3%) of <1-c> .
