Procedure

50 g of 5-(dioxolan-2-yl)-4,4-dimethylvaleronitrile, prepared in D], are dissolved in 1.3 l of acetone in the presence of 140 ml of concentrated hydrochloric acid and 700 ml of water. The mixture is stirred at room temperature for 5 hours, the acetone is concentrated under vacuum and the residue is taken up with ether, washed with water and then evaporated to dryness to give 35 g of 5-formyl-4,4-dimethylvaleronitrile.
