EDCI (48 mg, 0.25 mmol) was added to a mixture of the 1-(4-fluorophenyl)-2-oxoazepane-3-carboxylic acid (21 mg, 0.084 mmol) and HOBT (34 mg, 0.25 mmol) in DMF (0.5 mL) at ambient temperature, and the reaction mixture was stirred for 10 minutes at ambient temperature. 1-(4-methoxybenzyl)-4-(4-amino-2-fluorophenoxy)-N-(1-methylpiperidin-4-yl)-1H-pyrazolo[3,4-b]pyridin-3-amine (20 mg, 0.042 mmol, obtained from Example 101, Step A) and triethylamine (0.035 ml, 0.25 mmol) were added. The resulting mixture was stirred for 12 hours at ambient temperature. The reaction mixture was diluted with EtOAc. The organic layer washed with 10% aqueous LiCl, dried over Na2SO4, and concentrated. The residue was purified by flash column chromatography (5% MeOH in CH2Cl2) to afford the product (20 mg, 67% yield) as a white solid. LRMS (APCI pos) m/e 710.3 (M+1).
