Versuchsvorschrift

2,4-Diamino-6-chloro-s-triazine (2.25 g, 15.0 mmol) was added to a solution of sodium (0.43 g, 18.8 mmol) in benzyl alcohol (30 mL) under argon. The suspension was heated in a 130° C. oil bath for 3.5 h. The excess benzyl alcohol was removed under vacuum and the resulting solid was collected with the aid of benzene, and washed with water (100 mL): yield, 1.83 g (56%); mp 184-185° C. (lit. 186-188° C.; Wakabayashi et al. Nippon Dojo-Hiryogaku Zasshi, 41, 193-200 (1970) ); UV (pH 1) λmax 233 nm (sh) (ε=0.589×104); (pH 6.9) 238 (sh) (0.111×104); (pH 13) 240 (sh) (0.073×104); 1H NMR δ 5.25 (s, 2H, ArCH2), 6.63 (s, 4H, NH2, exchange with D2O), 7.30-7.42 (m, 5H, ArH); MS (EI) calcd. m/z for C10H11N5O 217.0963, found 217.0955.
