Procedure
Isoamyl nitrite (140 g) was added to a suspension of 7-chloro-2-methylimidazo[2,1-a]isoquinoline (17.1 g) in dioxane (170 ml) at 50° C. and the mixture was refluxed for 15 minutes. After being cooled, the resulting precipitate was collected by filtration, washed successively with dioxane and diethyl ether and dried in a desiccator to give 7-chloro-2-methyl-3-nitrosoimidazo[2,1-a]isoquinoline (7.7 g).
