PROCEDURE

实验过程

More specifically, to prepare ST-246 monohydrate, Form I, cycloheptatriene is reacted with maleic anhydride in the presence of toluene to yield the major product, endo isomer. The exo isomer is further produced from about 7% to 0.6% by crystallization from toluene/heptane. Further, hydrazine in the anhydrous or hydrate form is reacted with Methyl 4-(trifluoromethyl)benzoate in the presence of isopropanol to yield (4-(trifluoromethyl)-benzhydrazide. The product is then crystallized from isopropanol.
