Procedure

To a mixture of 1-(7H-pyrrolo[2,3-d]pyrimidin-4-yl)-4-piperidinamine D2 (65.2 mg), 5-pyrimidinecarboxylic acid (37.2 mg, 0.300 mmol), HATU (137 mg, 0.360 mmol) and HOAt (24.50 mg, 0.180 mmol) in DMF (1.5 mL) was added DIPEA (252 μL, 1.440 mmol). The reaction mixture was stirred at room temperature until reaction was complete then solvent was removed in vacuo. The crude mixture was purified by MDAP using a high pH method to afford E14 (21 mg), 1H NMR (d6-DMSO) δ 11.70 (1H, brs), 9.30 (1H, s), 9.15 (2H, s), 8.65 (1H, d), 8.17 (1H, s), 7.17 (1H, d), 6.60 (1H, d), 4.65 (2H, dt), 4.15 (1H, m), 3.25 (2H, dt), 1.90 (2H, m), 1.55 (2H, m), MS(ES+) 324 [M+H]+.
