Reaction Steps
To a solution of 3.48 9 of 2'-carboxymethoxy-4'-(3-methyl-2-butenyloxy)acetophenone and 2.80 g of 4-n-heptylbenzaldehyde in 120 ml of ethanol was added 3.5 g of potassium hydroxide, and the mixture was stirred for 5 hours. After neutralization with dilute sulfuric acid, the resulting precipitate was collected by filtration, washed with water, dried and recrystallized from ethanol to give 4.10 g of 2'-carboxymethoxy-4-n-heptyl-4'-(3-methyl-2-butenyloxy)chalcone as pale yellow needles.
