Reaction Steps

A solution of 1.04 g (4.88 mmol) of (±)-cis-6-(cyanomethyl)-1,3-dioxane-4-acetic acid in 100 mL of methanol saturated with anhydrous ammonia is added to PG,75 a Parr shaker bottle Containing 0.53 g of water wet Raney nickel #30. The solution is heated at 45° C. and 50 pounds per square inch gage (psig) hydrogen pressure for 17 hours. The suspension is cooled and filtered to remove the Raney nickel through filter aid and the precipitate washed with methanol. The filtrate is concentrated at reduced pressure. The residue is dissolved in methanol saturated with anhydrous ammonia, treated with decolorizing charcoal, filtered through filter aid and evaporated to give 0.56 g of (±)-cis-6-(2-aminoethyl)-1,3-dioxane-4-acetic acid.
