    摘要: 2-Aromatic-3-HALobenzothizepines are prepared by reaction of a 2,3-dihydro-2-aromatic-3-hydroxybenzothiazepine with a thionyl HALide. For example, dl-cis-2-(4-methoxyphenyl)-2,3-dihydro-3-hydroxy-1, 5-benzothiazzepin-4(5H)-one relfuxed with thionyl chloride can prepare E-2-(4-methoxyphenyl)-3-chloro-1,5-benzothiazepin-4(5H)-one in 66 percent yield.
