Procedure
To a solution of 14.5 gm (10.3 mmol) 2-(3-Cyanopropyl)-1,3-dioxolane in anhydrous ammonia and ethanol was added 5% ruthenium on aluminum oxide. The reaction mixture was hydrogenated with an initial hydrogen pressure of 100 p.s.i. at ambient temperature for 32 hours. The reaction mixture was filtered and the filtrate concentrated under reduced pressure. The residue was purified by silica gel chromatography to give 12.0 gm (80.5%) of the product. MS (FD+) (m/e): 146.
