Procedure
A mixture of (R)-tert-butyl 2-bromo-4-(1-(2,2-difluoroethyl)-5-(4-(2,2,2-trifluoro-N-methylacetamido)azepan-1-yl)-1H-pyrazol-4-ylcarbamoyl)thiazol-5-ylcarbamate (200 mg, 0.29 mmol), Na2CO3 (62 mg, 0.59 mmol) and 2,5-difluorobenzeneboronic acid (66 mg, 0.41 mmol) in DME (3 mL) and water (1 mL) was degassed by gently bubbling nitrogen through the mixture for 5 min. [1,1′-Bis(diphenylphosphino)ferrocene]dichloro-palladium(II) (30 mg, 0.037 mmol) was then added and the mixture heated in a microwave at 120° C. for 60 min. The solvents were removed under reduced pressure and the residue dissolved in a solution of HCl in 1,4-dioxane (4 M, 5 mL) and MeOH (5 mL) and stirred at 70° C. for 48 hr. The solvent was removed under reduced pressure and the residue dissolved in MeOH/DCM and passed through an SCX cartridge washing with DCM and MeOH and eluting with 1 N ammonia in MeOH. The solvent was removed under reduced pressure and the residue purified by preparative HPLC to yield 108 as the mono formate salt as a pale brown solid (21 mg, 14% over two steps). 1H NMR (400 MHz, d4-MeOD) δ 8.53 (s, 1H), 8.15-7.95 (m, 1H), 7.58 (s, 1H), 7.35-7.05 (m, 2H), 6.25 (tt, J=55.6, 4.1 Hz, 1H), 4.54-4.43 (m, 2H), 3.43-3.22 (m, 5H), 2.68 (s, 3H), 2.28-1.74 (m, 6H). LCMS (ES+) m/z 512 (M+1).
