Reaction Steps

A solution of {(S)-1-[6-fluoro-1-(2-methoxyethyl)-7-pyridin-2-yl-1H-benzoimidazol-2-yl]ethyl}carbamic acid tert-butyl ester (231 mg, 0.56 mmol) in TFA (2 mL) and DCM (6 mL) was stirred for 45 min at RT. The reaction mixture was 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 to afford the title compound as a pale yellow oil (179 mg, 99%). Marfey's test: >99% de. LCMS (Method C): RT 1.76 min [M+H]+ 315. 1H NMR (CDCl3, 400 MHz): δ 8.75 (1H, ddd, J=5.0, 2.0, 1.0 Hz), 7.84 (1H, ddd, J=7.5, 7.5, 2.0 Hz), 7.73 (1H, dd, J=9.0, 5.0 Hz), 7.60-7.57 (1H, m), 7.38 (1H, ddd, J=7.5, 5.0, 1.0 Hz), 7.09 (1H, dd, J=10.0, 9.0 Hz), 4.33 (1H, q, J=6.5 Hz), 4.12 (1H, ddd, J=15.5, 5.5, 4.5 Hz), 4.02 (1H, ddd, J=15.5, 7.0, 5.0 Hz), 3.12-3.01 (2H, m), 3.06 (3H, m), 2.00 (2H, bs), 1.59 (3H, d, J=6.5 Hz).
