Procedure

To a mixture of 1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-4-piperidinamine D2 (100 mg), 4-pyridinecarboxylic acid (56.7 mg, 0.460 mmol), HATU (210 mg, 0.552 mmol) and HOAt (37.60 mg, 0.276 mmol) in DMF (2.3 mL) was added DIPEA (386 μL, 2.209 mmol). The reaction mixture was stirred at room temperature for 2 hours then the solvent was removed in vacuo. The crude mixture was purified by MDAP using a high pH method to afford E11 (75 mg), 1H NMR (d6-DMSO) δ 11.70 (1H, brs), 8.70 (2H, d), 8.57 (1H, d), 8.17 (1H, s), 7.72 (2H, d), 7.18 (1H, d), 6.60 (1H, d), 4.70 (2H, dt), 4.15 (1H, m), 3.20 (2H, dt), 1.90 (2H, m), 1.60 (2H, m), MS(ES+) 323 [M+H]+.
