合成路线1
该中间体在本合成路线中的序号：(IX)The condensation of 4-(tert-butoxycarbonylamino)-1-methyl-1H-pyrrole-2-carboxylic acid (I) with 4-amino-1-methyl-1H-pyrrole-2-carboxylic acid methyl ester (II) by means of DCC, HOBT and TEA in hot DMF gives the dimeric amide (III), which is hydrolyzed with NaOH in hot methanol/water to yield the carboxylic acid (IV). The condensation of (IV) with methyl ester (II) by means of HBTU and TEA in hot DMF affords the trimeric diamide (V), which is hydrolyzed with NaOH in methanol/water to provide the carboxylic acid (VI). The deprotection of the carbamate group of (VI) with HCl in ethyl acetate gives the trimeric amino acid (VII), which is condensed with 4,5-dichloroisothiazole-3-carboxylic acid (VIII) by means of HBTU and DIEA in DMF to yield the tetrameric carboxylic acid (IX). The condensation of (IX) with 3-aminopropionitrile (X) by means of HBTU and TEA in DMF affords the corresponding tetrameric tetraamide (XI), which is treated with gaseous HCl in methanol to provide the iminoester (XII). Finally, this compound is treated with NH3 in methanol to furnish the target carboxamidine.
