Procedure

10 g of 2,2,5,5-tetramethylcyclopentylidenemethyl methyl ether was dissolved in 100 ml of tetrahydrofuran, and 50 ml of 6N-hydrochloric acid was added thereto. The mixture was vigorously stirred at room temperature for 3 hours, and then treated in the same manner as in Example 11 to obtain 8.60 g of 1-formyl-2,2,5,5-tetramethylcyclopentane. Yield 94%.
