Procedure

567 g of 2-n-pentyl-(1-carbomethoxy-2-oxopropyl)-1-cyclopentanone were hydrolysed using an equal weight of water according to the method described in Example 1 (b). There were obtained 391 g of 2-n-pentyl-3-(2-oxopropyl)-1-cyclopentanone (overall yield = 80% based on the amount of 2-n-pentyl-cyclopent-2-en-1-one consumed) having the physical constants shown in Example 1 (b).
