A solution of 6-[7-(hydroxymethyl)-4-(morpholin-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-5-yl]pyridine-2-carbonitrile (C11) (from the previous step, 85 mg, ≦0.25 mmol) in acetonitrile (3 mL) was brought to a pH of >12 via addition of solid potassium carbonate. After 30 minutes at room temperature, the reaction mixture was filtered and concentrated in vacuo. Purification via preparative HPLC (Column: Phenomenex Gemini C18, 8 μm; Mobile phase A: ammonia in water, pH 10; Mobile phase B: acetonitrile; Gradient: 10% to 50% B) afforded the product as a white solid. Yield: 15.2 mg, 49.6 μmol, 20% over two steps. LCMS m/z 307.2 [M+H+]. 1H NMR (400 MHz, DMSO-d6) δ 8.38 (s, 1H), 8.13 (dd, J=8.1, 7.7 Hz, 1H), 7.96 (br d, J=8 Hz, 1H), 7.89 (br d, J=8 Hz, 1H), 7.86 (s, 1H), 3.50-3.55 (m, 4H), 3.19-3.24 (m, 4H).
