摘要：

A crystal form A of 3-(6-(1-(2,2-difluorobenzo[D][1,3]dioxole-5-yl)cyclopropane formamido)-3-methylpyridine-2-yl)benzoic acid and preparation method thereof. The crystal form A has a low hygroscopicity, convenience for storage, good stability, and higher solubility than the prior art, and therefore plays an important role in future optimization and development of the drug.
