Procedure

A mixture of 5-[3-(tetrahydro-pyran-2-yloxy)-prop-1-ynyl]-3H-isobenzofuran-1-one (1.0 g, 3.67 mmol) and 10% palladium on carbon (200 mg) in MeOH (15 ml) was shaken under 45 psi of hydrogen for 20 hours. The catalyst was removed by filtration through celite and rinsed with MeOH. The combined filtrates were evaporated to give 5-[3-(tetrahydro-pyran-2-yloxy)-propyl]-3H-isobenzofuran-1-one as a light yellow oil (1.0 g, 99%).
