Reaction Steps

A mixture of (S)-1-[1-(trans-3-benzyloxycyclobutyl)-6-fluoro-1H-benzoimidazol-2-yl]ethylamine (67 mg, 0.20 mmol), 4-amino-6-chloropyrimidine-5-carbonitrile (31 mg, 0.20 mmol) and DIPEA (0.18 mL, 0.99 mmol) in IPA (3 mL) was heated at 90° C. in a sealed vial for 16 h. After cooling to RT, the reaction mixture was concentrated in vacuo, dissolved in DCM and loaded onto an Isolute® SCX-2 cartridge which was washed with DCM then MeOH and then 2M NH3/MeOH. The product containing fractions were combined and concentrated in vacuo. The resulting residue was purified by column chromatography (Si—PCC, gradient 0-5% 2M NH3/MeOH in DCM) to afford the title compound as a colourless glassy solid (60 mg, 67%). LCMS (Method B): RT 3.09 min [M+H]+ 458
