2-(Methylsulfonyl)-4-(1-tosyl-5-(trifluoromethyl)-1H-pyrrolo[2,3-b]pyridin-3-yl)pyrimidine-5-carbonitrile (160.2 mg, 0.255 mmol) was added to a solution of 4-(5-(1-aminoethyl)pyridin-2-yl)-1-methylpiperidin-4-ol (66.01 mg, 0.28 mmol) in tetrahydrofuran (8 mL). The reaction mixture was stirred under nitrogen at room temperature for 18 hours. 1M Lithium hydroxide (1.020 mL of 1 M, 1.020 mmol) was added and the reaction mixture was stirred at room temperature for 4 hours. The crude mixture was partitioned between ethyl acetate and brine. The organic extracts were dried over magnesium sulfate, filtered and concentrated in vacuo. The residue was purified by reverse phase preparative HPLC [Waters Sunfire C18, 10 μM, 100 Å column, gradient 10%-95% B (solvent A: 0.05% TFA in water; solvent B: CH3CN) over 16 minutes at 25 mL/min]. The fractions were collected, passed through a sodium bicarbonate cartridge and freeze-dried to give the title compound as a white solid (12.5 mg, 9% yield).
