Reaction Steps

A solution of 2-methyl resorcinol (1 eq) and p-methoxy phenyl acetic acid (1 eq) in boron trifluoride diethyl etherate (8 eq) was refluxed for 3½ h, whilst stirring, under nitrogen. The brown solution was allowed to cool to room temperature, quenched with NaOAc solution (10% w/v) and left to stand overnight. The resultant precipitate was filtered, washed with water and dried to give 1-(2,4-dihydroxy-3-methyl-phenyl)-2-(4-methoxy-phenyl)-ethanone as a solid.
