実験手順

A mixture of 1-methyl-N5 -[3-[3-[(dimethylamino)methyl]phenoxy]propyl]-1H-1,2,4-triazole-3,5-diamine (1.0 g), acetic anhydride (0.35 g) and pyridine (50 ml) was stirred at 25° for 12 h. The pyridine was removed and the residue was dissolved in ethyl acetate. The organic solution was washed with aqueous sodium carbonate and evaporated to give the title compound as a pale yellow oil (1.1 g). TLC silica, methanol/0.88 ammonia 80:1, Rf 0.49. NMR (CDCl3) 1.42 brs (1H); 2.81 m (1H); 3-3.4 m (3H); 5.34 t (1H); 5.98 t (2H); 6.52 s (3H); 6.65 s (2H); 6.5 m (2H); 7.8 s (6H); 7.5-8.1 m (2H); 7.9 s (3H).
