tert-Butyl((1R,2R)-2-{[(2-Chloro-6H-thieno[2,3-b]pyrrol-5-yl)carbonyl]amino}-2,3-dihydro-1H-inden-1-yl)carbamate (Method 22, 10.6 g, 24.5 mmol) was suspended in DCM (200 mL), TFA (20 mL) added and the reaction stirred at ambient temperature for 20 hours. The volatiles were removed by evaporation under reduced pressure and the residue triturated with DCM (50 mL) then filtered and dried to give the title compound (10.9 g, 100%) as the trifluoroacetic acid salt.
