Reaction Steps
A mixture of (±)-cis-1-methylethyl 6-(cyanomethyl)-2,2-dimethyl-1,3-dioxane-4-acetate, 0.55 g, in glacial acetic acid is hydrogenated with platinum dioxide at 50 pounds per square inch (PSI). Concentration, dilution with ethyl acetate and bicarbonate wash, followed by washing with brine and drying provides 250 mg of (±)-cis-1-methylethyl 6-(2-aminoethyl)-2,2-dimethyl-1,3-dioxane-4-acetate. MS 260.1, 244.1
