Versuchsvorschrift

A solution of 1-(tetrahydro-pyran-2-yloxy)-propan-2-one (126.6 g, 0.8 mol), ammonium chloride (65.8 g, 1.23 mol) and sodium cyanide (45.5 g, 0.92 mol) in a solution of aqueous ammonia (920 ml, 28%) is stirred vigorously at room temperature for 5 hours. The aqueous phase is extracted repeatedly with ethyl acetate. The collected organic extracts are dried and the solvent is evaporated under reduced pressure to give the 2-amino-2-methyl-3-(tetrahydro-pyran-2-yloxy)-propionitrile (130 g, 88.2%) as a liquid.
