Mode opératoire

The procedure is as above, with dibromododecane and 2-amino-4-para-tolylpyridine, which is synthesized according to Chambron J.Cl. Strasbourg Tetrah. 1987 43 (5) 895/905. The product obtained is purified in the base state on a silica column with a benzene/ethyl acetate mixture. It is reconverted to the hydrobromide with a mixture of ether and an isopropanol solution of hydrogen bromide. It can then be recrystallized.
