Versuchsvorschrift

Tetraethylammonium cyanide (142.3 g, 910.8 mmol) was added portionwise over 10 minutes to a solution of [2-(dimethoxymethyl)-3,3-dimethoxypropyl]methanesulfonate (124 g, 455.4 mmol) in MeCN (1.24 L). The reaction mixture was stirred at room temperature for 72 h, then portioned between ethyl acetate (1.24 L) and water (1.24 L). The layers were separated and the organic layer was isolated, washed with brine. The organics were dried over MgSO4, filtered and evaporated to give 3-(dimethoxymethyl)-4,4-dimethoxybutanenitrile 11 as a dark brown oil (86.1 g).
