Reaction Steps

A solution of (4R-cis)-6-(cyanomethyl)-2,2-dimethyl-N,N-bis(phenylmethyl)-1,3-dioxane-4-acetamide (10 0 g, 0.025 mol) in methanol (150 mL) containing anhydrous ammonia (2.25 g) is reacted with hydrogen gas in a Parr shaker at 30° C. in a presence of a slurry of Raney nickel A-7000 (3.7 g). After 3 hours, uptake of hydrogen has ceased, the mixture is cooled to 20° C., the atmosphere is vented and exchanged for nitrogen, the slurry is filtered through celite, and concentrated at reduced pressure to give 9.4 g of (4R-cis)-6-(2-aminoethyl)-2,2-dimethyl-N,N-bis(phenylmethyl)-1,3-dioxane-4-acetamide as an oil;
