The solution was then heated at reflux for A hour, cooled to 70°C and 4-methylpentan-2-one (2 liters) added. The water was removed by azeotropic distillation under reduced pressure (260 torrs) and the resultant solution treated with charcoal (10 g) at 50°C. The solution was filtered and cooled to 10°C. N-[2-[ [ [5-dimethylamino)methyl-2-furanyl] methyl] thio] ethyl] -N -methyl-2-nitro-1,1 -ethenediamine (380 g) was filtered off and dried, melting point 69°C to 70°C.

Neben Oxiranen oder 2-Oxo-l,3-dioxolan werden zur N-Alkylierung von Imidazolen manch-mal auch andere Heterocyclen verwendet, die in der Lage sind, unter Ringoffnung Nukleophile zu addieren. So kann 2-Methyl-4(5)-nitro-imidazol mit l,2-Oxathiolan-2,2,-dioxid (Propansul-ton) zu 2-Methyl-5-nitro-l-(3-sulfo-propyl)-imidazol (48%) und mit 2-Oxo-oxetan zu l-(2-Carboxy-ethyl)-2-methyl-4-nitro-imidazol umgesetzt werden875.

As seen from Table 3.41, the half-wave potentials of 3(5)-nitropyrazole and l-methyl-3-nitropyrazole are practically identical at all pH values. In the authors opinion, this may be due to the fact that 3(5)-nitropyrazole contains, mainly, 3-nitro tautomer [904], A similar regularity is observed for 4(5)-nitroimidazole and 1-methyl-4-nitroimidazole [903], The E1/2 values of l-methyl-3-nitropyrazole lie in more a negative region than those of l-methyl-5-nitropyrazole. Probably it is related to the fact that nitro group in 1-methyl-3-nitropyrazole is located near electron-donative pyridine nitrogen atom (N-2). This is also the case for imidazoles l-methyl-4-nitro- and 1 -methyl-5-nitroimidazole.
