Reaction Steps

A solution of 58.0 g (0.299 mole) of 2,4-dihydroxy-3-propylacetophenone and 29.5 ml (0.36 mole) of pyrrolidine in 250 ml of toluene was heated to reflux for three hours under a Dean-Stark trap. After cooling the mixture, 68.2 ml (0.48 mole) of ethyl levulinate was added and the mixture was refluxed for two hours. An additional 10 ml (0.12 mole) of pyrrolidine was added and the mixture was refluxed overnight under a Dean-Stark trap.
