Procedure

1-(2'-cyanoethyl)-2,2,4-trimethyl decahydroquinoline was prepared via the post-reaction of the above chloroethyl substituted compound. 61.0 grams (0.25 mole) of 1-(2'-chloroethyl)-2,2,4-trimethyl decahydroquinoline dissolved in 50 milliliters of methyl sulfoxide was added dropwise over a period of 40 minutes at room temperature to a prepared solution of 12.25 grams (0.25 mole) of sodium cyanide in 150 milliliters of methyl sulfoxide. The mix was then heated to 95° C. and stirred for 2.5 hours. The reaction mixture was then cooled, poured into 500 milliliters of ice water, diethyl ether was added, the organic layer separated out. The aqueous layer was washed with four 100 milliliter portions of diethyl ether and the ether washes combined with the original organic layer. The solution was then concentrated and distilled using a 6" Vigreaux column to yield 43.0 grams of a liquid product boiling at 134°-136° C. at 3.3 mm Hg. The infrared spectrum of the product is consistent with the desired compound, 1-(2'-cyanoethyl)-2,2,4-trimethyl decahydroquinoline. Calculated values for the formula C15H26N2 are 76.87% carbon, 11.18% hydrogen, and 11.95% nitrogen and found contents were 76.71% carbon, 11.02% hydrogen, and 11.15% nitrogen.
