合成路线1
该中间体在本合成路线中的序号:(IV)LM-1554 is synthesized by condensation of 2-amino-3-carbethoxy-4,5,6,7-tetrahydrobenzo[b]thiophene (I) with chloroacetonitrile (III) in the presence of dry hydrogen chloride gas followed by basification. Alternatively, 2-amino-3-carbamoyl-4,5,6,7-tetrahydrobenzo[b]thiophene (IV) can be condensed with chloroacetonitrile (III) under the above reaction conditions. The condensation of (I) with chloroacetamide (II) in the presence of an equivalent of phosphorus oxychloride in chloroform followed by basification also yields LM-1554.
