合成路线1
该中间体在本合成路线中的序号：(III)Reaction of the Grignard reagent prepared from 2-fluorobenzyl bromide (I) and Mg in ether with cyclopropyl cyanide (II) in the same solvent gives 1-cyclopropyl-2-(2-fluorophenyl)ethanone (III), which is brominated with Br2 in CCl4 to yield the a-bromoketone (IV). Condensation of ketone (IV) with 2,3,4,5,6,7-hexahydrothieno[3,2-c]pyridin-2-one hydrochloride (V) by means of K2CO3 in DMF affords the adduct (VI), which is finally treated with acetic anhydride and NaH in DMF.
