Reaction Steps

A mixture of 21.1 grams of 5-(2-azapentyl)-5-methyl-2,4,6-triethylhexahydropyrimidine, prepared as described in example 1, 25 grams of conc. HCl and 25 grams of water was refluxed for 2 hours. The organic layer which separated was removed and discarded and the aqueous solution after extraction with ether was basified with a sodium hydroxide solution. The organic layer which separated was removed and the aqueous phase extracted with ether. The ethereal solution was combined with the organic layer and after drying evaporated under diminished pressure to yield 15.0 grams of 7-amino-6-(1-aminopropyl)-6-methyl-4-azanonane; b.p. 72°-76° C./0.05 torr; Infrared spectrum, 2.97 and 3.05μ (N-H) and 6.15μ (NH2); 'H nuclear magnetic resonance spectrum, solvent CDCl3, internal reference tetramethylsilane, δ in ppm: 3.07-2.30, 6H; 2.00-1.14, 6H; 1.14-0.67, 12H. 13C nuclear magnetic resonance spectrum, solvent CDCl3, internal reference tetramethylsilane, δ in ppm: ##STR7## 11.9(1); 23.2(2); 52.9 and 52.8(3); 54.7 and 54.3(5); 42.9 and 43.1(6); 58.8, 56.7 and 57.5(7,11); 24.9, 24.7 and 25.7(8,12); 12.2(9,13); 19.2 and 17.0(10).
