Reaction Steps

4-(4-Hydroxyphenyl)-2-butanone (49 g) was added by portions while warming to a stirred solution of potassium hydroxide (0.33 m) in 15 ml of water. To this was added dropwise, 49.8 g of 1-bromopentane and the resultant mixture was stirred at reflux temperature overnight. The mixture was allowed to cool after which 500 ml of 20% sodium hydroxide was added and the resultant mixture was stirred an additional 30 minutes followed by extraction with ethylacetate. The organic extracts were dried and evaporated to yield approximately 63 g of the desired 4-(4-pentoxyphenyl)-2-butanone which was used to prepare the title compound as follows.
