Procedure

A mixture of tert-butyl (1-{4-[2-(2-aminopyridin-3-yl)-5-chloro-3H-imidazo[4,5-b]pyridin-3-yl]phenyl}cyclobutyl)carbamate (50.0 mg, 0.101 mmol), 4-[3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl]thiomorpholine 1,1-dioxide (51.5 mg, 0.153 mmol), Pd(dppf)2Cl2.DCM (8.32 mg, 0.0102 mmol), and 2M NaOH aq. (0.150 mL, 0.310) in DME (2 mL) was heated at 80° C. for 10 hours under nitrogen. After cooling to room temperature, the mixture was diluted with DCM and filtered through a Celite pad. The combined filtrate and washings were concentrated. The residue was purified by silica gel column chromatography (CHCl3/EtOAc=2:1→1:1→1:2) to afford desired product (38.4 mg, 56.6%) as pale yellow foam.
