合成路线1
该中间体在本合成路线中的序号:(V)Chlorination of carboxylic acid (I) with SOCl2 in the presence of NMP in THF/toluene, followed by condensation of the resulting acid chloride with the amine HCl (II) or its free base using DIEA in THF, provides the carboxamide (IVa) . Alternatively, condensation of carboxylic acid (I) with the amino esters (IIIa) or (IIIb) by means of HATU and Et3N or DIEA in DMSO affords the corresponding carboxamides (IVb) or (IVc) . Finally, butyl (IVa) ,methyl (IVb) or ethyl (IVc) esters are hydrolyzed with aqueous NaOH in THF/MeOH at 67 °C or DMSO , and then treated with aqueous NaOH in THF .
