该中间体在本合成路线中的序号：(VII)

By condensation of 2-bromo-6-methoxynaphthalene (I) with 3-buten-2-ol (VI) catalyzed by Pd(OAc)2 or PdCl2, along with PPh3 and NaHCO3 in 1-methyl-2-pyrrolidone at 140 C. The reaction of 2-bromo-6-methoxynaphthalene (I) with Mg in THF gives the expected Grignard reagent (VII), which is then condensed with 3-buten-2-one (II) by means of ZnCl2-amine complex in the same solvent.
