Procedure

3-Hydroxy-1-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]cyclobutylacetonitrile (0.020 g, 0.000046 mol) was treated with trifluoroacetic acid (0.5 mL, 0.006 mol) at rt for 30 min and evaporated to dry. The resultant residue was mixed with ethylenediamine (0.2 mL, 0.003 mol) in MeOH (1 mL) for 2 h. The reaction was concentrated and purified on prep. LCMS (pH=10) to give 2 isomers of the desired products. First peak retention time 0.714 min, LCMS calculated for C15H15N6O(M+H)+: 295.1; Found: 295.3. Second peak retention time 0.750 min, LCMS calculated for C15H15N6O(M+H)+: 295.1; Found: 295.3. 1H NMR (400 MHz, CD3OD): δ 8.67 (1H, s), 8.66 (1H, s), 8.38 (1H, s), 7.51 (1H, d, J=3.6 Hz), 6.98 (1H, d, J=3.6 Hz), 4.37 (1H, s), 3.34 (2H, s), 3.22 (2H, m), 2.48 (2H, m) ppm.
