Versuchsvorschrift
To a solution of N-(2-aminophenyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine-2-carboxamide (1.0 eq) obtained in step VIII of example 203 in DMF was treated with Carbonic acid 3,4-dimethoxy-phenyl ester 4-nitro-phenyl ester (1.0 eq) in presence of base like Et3N and stirred at 50° C. for 8 h Reaction was then quenched with water and extracted with ethyl acetate and the organic layer was separated, dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford crude product, which, on purification by column chromatography afforded the title compound.
