合成路线1
该中间体在本合成路线中的序号：(IX)The synthesis of GYKI-13504 is as follows: Trifluoroacetophenone (I) is reacted with triphenylbenzyl phosphonium chloride (II) in the presence of sodium methylate and this reaction yields stilbene (III). Stilbene (III) is then hydrogenized in the presence of charcoal palladium catalyzer and the yielded propane derivative (IV) is brominated with 1,2-dibromoethane. The brominated compound (V) is reacted with anizole (A) according to the Friedel Crafts' reaction. The yield (VI) is treated with pyridine hydrochloride and the phenol derivative (VII) is reacted with 2-chloroethanol tosylate (VIII) in the presence of potassium hydroxide. The chloroethoxy (IX) is treated with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) and the (E)-isomer (X) is obtained with fractionated crystallization. This latter product is reacted with 2-aminoethanol (B) to obtain the end product GYKI-13504.
