Participants

Reaction Steps

Combine (2-{2-[5-fluoro-2-(2-[1,2,3]triazol-1-yl-ethylamino)-pyrimidin-4-yl]-benzo[b]thiophen-7-yl}-benzyl)-carbamic acid tert-butyl ester (100 mg, 0.18 mmol) and dry TFA acid (2.0 mL) in dry DCM (2.2 mL). Stir the solution at RT for 1 h. Remove the solvent. Add DCM, wash with saturated sodium bicarbonate solution, water, and aqueous saturated sodium chloride. Separate the organic layer and dry over magnesium sulfate. Filter and concentrate in vacuo. Purify the residue by column chromatography [0.1% to 2% 2 M ammonia in methanol/DCM] to give the title compound (78 mg, 96%). MS (ES) m/z 446 [M+1]+.
