Reaction Steps

To a stirred ice bath-cooled solution of 4.0 g. (0.020 mole) of 2,4-dimethyl-8-quinoline carboxylic acid in 20 ml. of N,N-dimethyl formamide is added 2.8 ml. of triethyl amine. To this solution is added dropwise 2 ml. of ethylchloroformate. The mixture is stirred for one hour, then 2 g. (0.020 mole) of 2-aminotetrazole monohydrate in 10 ml. of N,N-dimethylformamide is added. The mixture is stirred at 20° C. for about 16 hours then evaporated to provide a residue which is washed with water. The residue is recrystallized twice from acetic acid to provide 2,4-dimethyl-8-(1H-tetrazole-5-ylcarbamoyl)quinoline, m.p. 300°-305° C.
