Procedure
In a 4 liter jacketed reactor, a mixture of 1,236 liter of AcOH and 1,236 liter of water was heated to 45° C. Then to this mixture were added 494 g of methyl [2-(2,2-dimethoxyethyl)-3-oxocyclopentyl]acetate. The resulting reaction medium was stirred at 46-49° C. until completion of the conversion of the acetal to aldehyde. Distillation under vacuum allowed for the direct isolation of the purified title compound with a yield of 89% (overall yield from Example 1: 66%).
