Reaction Steps

A mixture of 3-cyanomethyl-2-methylimidazo[2,1-a]isoquinoline (2.8 g), ammonium chloride (0.74 g) and sodium azide (0.9 g) in N,N-dimethylformamide (28 ml) was heated at 120°-125° C. with stirring for 18 hours. The solution was poured into water, acidified with concentrated hydrochloric acid and then neutralized with an aqueous solution of sodium bicarbonate. The resulting precipitates were collected by filtration, washed with water and recrystallized from a mixture of chloroform and methanol to give 2-methyl-3-[(1H- tetrazol-5-yl)methyl]imidazo[2,1-a]isoquinoline (2.9 g).
