실험 절차

A solution of 4,5-dichloro-N-(1-methyl-1H-pyrazol-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-2-amine (85 mg, 0.30 mmol), (R)-tert-butyl piperidin-3-ylcarbamate (90 mg, 0.45 mmol) and DIEA (75 μL, 0.45 mmol) in DMSO (0.60 mL) was heated to 120° C. in a microwave for 10 min. The reaction solution was poured into water and filtered. The filtrate was extracted with EtOAc and the organic layer was dried over MgSO4, filtered and concentrated in vacuo. The solids were combined and purified via flash chromatography eluting with a gradient of 1%-5% of (10% NH4OH in MeOH) in DCM to give the title compound (59 mg, 44% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 11.38 (br. s., 1H), 8.74 (s, 1H), 7.82 (s, 1H), 7.49 (s, 1H), 7.04 (d, J=2.69 Hz, 1H), 6.89 (d, J=7.83 Hz, 1H), 3.96-4.11 (m, 2H), 3.78 (s, 3H), 3.51 (br. s., 1H), 2.85 (t, J=11.25 Hz, 1H), 2.75 (t, J=11.13 Hz, 1H), 1.85-1.94 (m, 1H), 1.75-1.84 (m, 1H), 1.70 (t, J=12.10 Hz, 1H), 1.38 (s, 9H), 1.31 (br. s., 1H). m/z (APCI+) for C20H27ClN8O2 447.2 (M+H)+.
