Procedure

A solution of 30.1 g of 4-(3-methoxyphenyl)-3-buten-2-one in 200 ml of MeOH was hydrogenated over 200 mg of 10% palladium on carbon for two hours. The catalyst was filtered and the solvent evaporated in vacuo to give 30.2 g of yellow oily 4-(3-methoxyphenyl)-2-butanone.

Workup

  1. filtrationThe catalyst was filtered
  2. customthe solvent evaporated in vacuo
