Reaction Steps
4-Amino-5-carbethoxy-1-methyl-2-phenyl imidazole (2.84) [made by the method of Cook et. al, Journal of the Chemical Society, 1950 (2775)] in 5N hydrochloric acid (24.0 ml) was cooled to 0° C and a cold solution of sodium nitrite (0.96 gm) in water (5 ml) added slowly, with stirring, keeping the mixture at 0° C. The resulting solution was added dropwise to a cold (0° C) mixture of sodium carbonate (120 mls of 30%) and dimethylamine (2.5 mls of 25% aqueous solution).
