Procedure

1-ethyl-2,2,4-trimethyl decahydroquinoline was prepared by the reaction of the intermediate saturated decahydroquinoline with the alkyl halide. 36.3 grams (0.2 mole) of 2,2,4-trimethyl decahydroquinoline of about 76% cis structure was placed into a reactor vessel equipped for heating and agitation. 15.6 grams (0.1 mole) of iodoethane was added dropwise to the reactor vessel. The mix was heated to 105° C. while stirring for 3 hours. A thick slurry formed which was filtered out and washed with acetone. The acetone wash liquid was then concentrated and distilled using a 3" Vigreaux column to yield 7.1 grams of a product boiling at 58°-60° C. at 0.25 mm Hg. The NMR spectra of the product was consistent with the desired product, 1-ethyl-2,2,4-trimethyl decahydroquinoline. Calculated carbon, hydrogen, nitrogen content for the formula C14H27N is 80.31% carbon, 13.00% hydrogen, and 6.69% nitrogen while the measured contents were 79.93% carbon, 13.54% hydrogen, and 6.35 % nitrogen respectively.
