To a solution of 6-[1-(3-hydroxy-2,2-dimethylpropanoyl)-1,2,3,6-tetrahydropyridin-4-yl]-N-1,3-benzothiazol-6-yl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (Example 110) (150 mg, 0.33 mmol) in DMSO (4 mL) was added EDC (190 mg, 1 mmol). The reaction mixture stirred at rt for 5 h. The mixture was taken up in a large amount of EtOAc and extracted with water. The combined organic extracts were dried over sodium sulfate and concentrated in vacuo, which afforded the title compound as a yellow solid. MS (ES+): m/z: 446.93 (100) [MH+]. HPLC: tr=2.53 min (ZQ2000: polar—5 min). 1H NMR (400 MHz, DMSO-d6): δ=1.37 (s, 6H) 3.39-3.69 (m, 3H), 3.70-4.22 (m, 3H), 6.21 (bs, 1H), 6.82 (s, 1H), 6.84 (d, J=1.6 Hz, 1H), 7.87 (dd, J=1.6, 8.8 Hz, 1H), 8.03 (d, J=8.8 Hz, 1H), 8.34 (s, 1H), 8.91 (d, J=2.0 Hz, 1H), 9.23 (s, 1H), 9.62 (s, 1H), 12.03 (s, 1H).
