该中间体在本合成路线中的序号:(XIII)The reaction of monoacid (VIII) with diphenylphosphoryl azide and triethylamine in refluxing tert-butanol gives the tert-butoxycarbonyl aminoester (XIII), which is deprotected with trifluoroacetic acid to yield the aminoester (XIV). The sulfonation of (XIV) with 4-chlorophenylsulfonyl chloride (XII) and triethylamine in dichloromethane affords the sulfonamido ester (XV), which is finally hydrolyzed with NaOH in refluxing methanol.
