Procedure

An isopropanolic solution (190 ml) of 24 g of 2-(6'-carbomethoxyhexyl)-3-methoxy-4-oxo-2-cyclopenten-1-one prepared in Step 1 and 2.85 g. of a 5% palladium carbon catalyst was subjected to catalytic hydrogenation under atmospheric pressure at room temperature until 2.3 liter of hydrogen gas was absorbed. The reaction mixture was treated according to a conventional method to give the desired compound, 2-(6'-carbomethoxyhexyl)-3-methoxy-4-hydroxy-2-cyclo-penten-1-one.
