XX, as a synthetic drug,  draw much attention to its synthetic methods. None of its synthesis within china has been reported so far, and those abroad beared such shorts as too strict reaction conditions, hardly-to-get raw materials, low total yield, and complex post-progressing.  This paper tried to search a synthesis technology route suitable for industrialized production, studying the reaction parameters such as temperature, time, and feeding ratio, determined the optimum ones, and gained a yield rather higher than ever reported.
