The structural formula of the compound is as shown in formula (I). 

Crystal form of small molecule immune compound, preparation method thereof and pharmaceutical composition containing the same

Provided are a new tubulin inhibitor and applications thereof, the tubulin inhibitor being a series of compounds based on substituted heterocyclic skeletons, targeting the colchicine binding sites of tubulin. The structure is: Formula (I), wherein: formula (A), n independently expresses an integer between 0 and 5, the condition being that n&#x2264;5, A represents mono- or poly-substituted groups, the groups being selected from the group consisting of H, C1-C20 amide group, C1-C20 acyloxy group, C1-C20 alkanoyl group, C1-C20 alkoxycarbonyl group, C1-C20 alkoxy group, C1-C20 alkylamino group, C1-C20 alkylcarboxyamino group, aroyl group, aralkanoyl group, carboxyl group, cyano group, halogen group, hydroxyl group, nitro group and methylthienyl group. 

Tubulin inhibitor

Provided is a composition of N-[4-[(3-chloro-4-fluorophenyl)amino]-7-[3-(ethoxy)-6-quinazolinyl]-4-(dimethylamino)-2-butenamide p-toluene sulfonate 1.5 hydrate &#x3b1;-polymorph. The &#x3b1;-polymorph has a stable form, a defined melting point, a good chemical stability, and a good endurance to high temperature and light irradiation, and is suitable for pharmaceutical use.
