Versuchsvorschrift

2,2,4,7-tetramethyldecahydroquinoline was prepared by reacting 125 grams of 2,2,4,7-tetramethyl-1,2-dihydroquinoline with hydrogen using 3 grams of rhodium at 5% by weight on charcoal as the catalyst and operating at 185° C., a 1000 psig pressure, for 24 hours. The desired product was confirmed by NMR spectral analysis and its carbon, hydrogen, nitrogen content (calculated contents for C13H25N is the same as above and analyzed contents were 78.95% carbon, 13.30% hydrogen, and 6.80% nitrogen). The product was 95% pure as determined by vapor pressure chromotograhy and boiled at about 65° C. at 1 mm of Hg.
