Reaction Steps

5,6,7,8-Tetrahydro-1-naphthylamine (Aldrich, 159 mg, 1.06 mmol), imidazoline-2-sulfonic acid (147.0 mg, 1.0 mmol, Compound 7 obtained as described above) and CH3CN (5 ml) were placed in a thick-walled cap which was sealed with a TEFLON™ screw and heated to 155° C. for 1.25 hours. The reaction mixture was cooled to room temperature and concentrated in vacuo. The resident was dissolved in CHCl3 and washed with aq. 1N NaOH ) to pH 13). The organic layer was separated, washed with brine, dried over Na2CO3 and concentrated in vacuo to yield a brown oil. The crude material was purified by flash chromatography (SiO2 ; 80:20 CHCl3 /CH3OH saturated with NH3) to yield 29.5 mg (14%) of the title compound as a white solid: mp 138°-141° C.; H NMR (300 MHz, CDCl3) σ 7.05 (t, 1H) 6.82 (m, 2H); 5.41 (br, 2H); 3.50 (s, 4H); 2.79 (m, 2H); 2.62 (m, 2H); 1.80 (m, 4H); Mass spectrum m/e 214.1339 (C13H16N3 requires 214.1344).
