Imidazo[1,5-a]pyridines in acetic acid solution are readily nitrated by nitric acid–sulphuric acid, although in some instances treatment of the base hydrogensulphate with nitric acid–acetic acid is preferred. Nitration occurs most readily in the 1-position, but 3-nitration occurs if the 1-position is already substituted.
乙酸溶液中的咪唑并[1,5- a ]吡啶很容易被硝酸-硫酸硝化,尽管在某些情况下,优选用硝酸-乙酸处理碱式硫酸氢盐。硝化作用最容易在1位发生,但如果1位已经被取代,则发生3位硝化。
