Participants

Reaction Steps

Step A Add 10% aqueous NaOH (38 mL) to a solution of p-anisaldehyde (25 mL, 0.206 mol) and acetophenone (23.97 mL, 0.206 mol) in EtOH (500 mL). Stir the mixture at room temperature over night. Dilute the mixture with water and extract with ether. Combine the ethereal extracts, wash with water and brine, dry over Na2SO4 and concentrate to a solid. Recrystallize the solid from ether/hexanes to provide 27.51 g (56%) of 4'-methoxychalcone, mp 72°-74° C.
