3-(Benzyloxy)-1-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]cyclobutylacetonitrile (0.024 g, 0.000046 mol) was treated with trifluoroacetic acid (0.5 mL, 0.006 mol) at rt for 30 min, then evaporated to dry. The residue was dissolved in MeOH (1 mL) and treated with ethylenediamine (0.2 mL, 0.003 mol) at rt for 2 h. The reaction mixture was concentrated in vacuo and the resulting residue purified on prep. HPLC (XBridge C18 column, eluting with a gradient of acetonitrile/water containing 0.15% NH4OH) to give 2 isomers of the desired products. First peak retention time 1.406 min; LCMS calculated for C22H21N6O(M+H)+: 385.2; Found: 385.3. 1H NMR (400 MHz, DMSO-d6): δ 12.10 (1H, br s), 8.71 (1H, s), 8.67 (1H, s), 8.38 (1H, s), 7.58 (1H, d, J=3.6 Hz), 7.33 (4H, m), 7.29 (1H, m), 7.05 (1H, d, J=3.6 Hz), 4.43 (2H, s), 4.23 (1H, m), 3.43 (2H, s), 2.78 (2H, m), 2.74 (2H, m) ppm. Second peak retention time 1.474 min, LCMS calculated for C22H21N6)(M+H)+: 385.2; Found: 385.3. 1H NMR (400 MHz, DMSO-d6): δ 12.10 (1H, br s), 8.79 (1H, s), 8.67 (1H, s), 8.39 (1H, s), 7.59 (1H, d, J=3.6 Hz), 7.34 (4H, m), 7.29 (1H, m), 7.06 (1H, d, J=3.6 Hz), 4.44 (2H, s), 4.14 (1H, m), 3.44 (2H, s), 3.16 (2H, m), 2.44 (2H, m) ppm.
