To a solution of [(R)-2-benzyloxy-1-(6-fluoro-1-pyridin-2-yl-1H-benzoimidazol-2-yl)ethyl]carbamic acid tert-butyl ester (420 mg, 0.91 mmol) in DCM (6 mL) was added TFA (3 mL) and the mixture stirred at RT for 2 h. The volatiles were removed in vacuo and the resulting residue loaded onto an Isolute® SCX-2 cartridge. The cartridge was washed with MeOH followed by 2M NH3/MeOH. The basic fractions were combined and concentrated in vacuo. The crude material was used in the following step without further purification. Yellow oil (284 mg, 86%). LCMS (Method B): RT 2.16 min [M+H]+ 363.20.
