Procedure

7.4 g of 2-(3,4-difluorophenyl)-6-(1-propynyl)naphthalene was dissolved in 80 ml of ethyl acetate. To the solution was then added 1.5 g of 5% palladium carbon. Hydrogen was then introduced into the reaction mixture at ordinary temperature and pressure. The reaction mixture was then stirred for 6 hours. The catalyst was then removed by filtration. The solvent was then distilled off to obtain 7.2 g of 2-(3,4-difluorophenyl)-6-propylnaphthalene. The product was then recrystallized from methanol to obtain 4.2 g of a purified product. (Cr 62.5 I)
