Procedure

A mixture of (R)-1-(6-fluoro-1-pyridin-2-yl-1H-benzoimidazol-2-yl)-2-methoxyethylamine (69 mg, 0.24 mmol), 4-amino-6-chloropyrimidine-5-carbonitrile (37 mg, 0.24 mmol) and DIPEA (0.21 mL, 1.2 mmol) in IPA (1 mL) was heated for 16 h at 90° C. After cooling to RT, the volatiles were removed under reduced pressure and the resulting residue was loaded onto an Isolute® SCX-2 cartridge. The cartridge was washed with MeOH followed by 2M NH3/MeOH. The basic fractions were combined, concentrated in vacuo and the resulting residue purified by column chromatography (Si—PCC, gradient 0-20% DCM in EtOAc) to afford 271 as a yellow solid (78 mg, 80%). LCMS (Method K): RT 3.52 min [M+H]+ 405.0. 1H NMR (DMSO-d6, 400 MHz): δ 8.68-8.64 (1H, m), 8.11 (1H, td, J=7.76, 1.94 Hz), 7.84 (1H, s), 7.79-7.73 (2H, m), 7.66 (1H, d, J=7.94 Hz), 7.56 (1H, ddd, J=7.52, 4.87, 0.98 Hz), 7.30-7.13 (4H, m), 6.03-5.95 (1H, m), 3.83 (2H, d, J=6.59 Hz), 3.19 (3H, s)
