Versuchsvorschrift
A solution of 72 mg (0.151 mmol) of (2-{[5-(Pyridin-2-ylmethoxy)-benzo[b]thiophene-2-carbonyl]-amino}-phenyl)-carbamic acid tert-butyl ester (52) in 1.0 ml trifluoroacetic acid was stirred for 45 min at room temperature and then added to an aqueous solution of sodium bicarbonate. After extraction with ethyl acetate and removal of the solvent the residue was recrystallized from ethyl acetate to yield 33 mg (0.88 mmol) 5-(Pyridin-2-ylmethoxy)-benzo[b]thiophene-2-carboxylic acid (2-amino-phenyl)-amide (51) as white solid, mp. 205–207° C.
