Reaction Conditions

Reaction Steps

To a solution of tetrahydropyran-4-one (150 g, 1.50 mol) in methanol (1500 mL) was added potassium cyanide (6.0 M in water, 400 mL, 2.4 mol), ammonium hydroxide (25% solution in water, 1000 mL, 7.4 mol), and ammonium chloride (161 g, 3.00 mol). The reaction mixture was heated to 70° C. After 16 hours, the reaction mixture was cooled, quenched with cold brine (2000 mL), and extracted with dichloromethane (4×1500 mL). The organic layers were combined, dried over anhydrous magnesium sulfate, filtered, and concentrated under reduced pressure to afford 4-amino-tetrahydro-2H-pyran-4-carbonitrile. The material was used without further purification.
