Procedure
4-Fluoro-1-isocyanato-2-methylbenzene (10 mg, 0.068 mmol) was added to a solution of 4-piperazin-1-yl-3-[4-(7-{[2-(trimethylsilyl)ethoxy]methyl}-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]butanenitrile hydrochloride (20 mg, 0.034 mmol; from Example 12, Step 2) and triethylamine (28 uL, 0.20 mmol) in THF (0.39 mL). The reaction was stirred for one hour, then solvent was removed in vacuo. The residue was stirred in a 1:1 mixture of DCM:TFA for 1 hour, concentrated, and stirred in a solution of methanol (1 mL) containing ethylenediamine (0.2 mL) for one hour. Purification via preparative HPLC-MS, eluting with a gradient of MeCN/H2O containing 0.15% NH4OH afforded product as the free base (11 mg, 67%). 1H NMR (400 MHz, d6-dmso): δ 12.12 (br s, 1H), 8.82 (s, 1H), 8.69 (s, 1H), 8.38 (s, 1H), 8.01 (s, 1H), 7.61 (d, 1H), 7.11 (dd, 1H), 7.02 (dd, 1H), 6.98 (d, 1H), 6.92 (dt, 1H), 5.01 (tt, 1H), 3.42-3.29 (m, 4H), 3.26-3.19 (m, 2H), 2.86 (dd, 1H), 2.81 (dd, 1H), 2.54-2.46 (m, 2H), 2.43-2.34 (m, 2H), 2.11 (s, 3H); LCMS (M+H)+: 488.3.
