Intermediate (VII) is prepared as follows. Hydrolysis of cis-azido-carbamate (XIV) using aqueous LiOH gives the corresponding carboxylic acid (XXXII), which is converted into carboxamide (XXXIII) by reaction with dimethylamine hydrochloride in the presence of EDC, HOBt and NMM in CH2Cl2. N-deprotection of carboxamide (XXXIII) with HCl in EtOH/CH2Cl2, followed by condensation of the resultant amine (XXXIV) with the lithium thiazolopyridinecarboxylate derivative (II) by means of EDC and HOBt in DMF provides amide (XXXV), which is finally reduced at the azido moiety by catalytic hydrogenation over Pd/C in MeOH .
