실험 절차

A mixture of N,N'-dimethyl-1,8-naphthalene diamine (prepared in Example 1) (0.50 g, 2.7 mmol, 186), tridecanal (0.56 g, 2.85 mmol. 197), p-toluenesulfonic acid (5 mg), and tetrahydrofuran (5 ml) was prepared and stirred at room temperature for 15 minutes. The mixture was basified with 25% sodium hydroxide (1.0 ml), diluted with water (20 ml) and extracted with ether (100 ml). The extract was dried over potassium carbonate, concentrated to give 2,3-dihydro-1,3-dimethyl-2-dodecyl perimidine as a solid: mp 30°-32° C.; NMR (CDCl3) 7.13(m, 4H), 6.32(d, 2H), 4.27(t, 1H), 3.02(s, 6H), 1.7-1.1(m, 22H), 0.85(t, 3H); IR (neat) 1595 cm-1.
