Procedure

To a suspension of benzothiazol-6-yl-[6-(1,2,3,6-tetrahydropyridin-4-yl)-7H-pyrrolo[2,3-d]pyrimidin-4-yl]amine trihydrochloride (50.0 mg, 0.11 mmol) in DMF (1.5 mL) was added N,N-diisopropylethylamine (0.04 mL, 0.20 mmol). The reaction mixture stirred at −20° C. for 5 min prior to the addition of 4-fluorophenyl isocyanate (9.5 mg, 0.07 mmol) in DMF (0.5 mL). The mixture was left to stir at rt for 1 h. The mixture was concentrated in vacuo and purified via MDP, which afforded the title compound as a white solid. MS (ES+): m/z: 485.88 (100) [MH+]. HPLC: tr=2.73 min (ZQ2000: polar—5 min). 1H NMR (400 MHz, CDCl3): δ=2.52-2.56 (m, 2H), 3.31 (s, 1H), 3.70 (t, 2H), 4.20 (s, 2H), 6.94 (m, 1H), 6.86 (d, J=0.8 Hz, 1H), 7.06-7.11 (m, 2H), 7.48-7.51 (m, 2H), 7.87 (dd, J=2.4, 8.8 Hz, 1H), 8.04 (d, J=8.8 Hz, 1H), 8.35 (s, 1H), 8.59 (s, 1H), 8.92 (d, J=2.0 Hz, 1H), 9.24 (s, 1H), 9.62 (s, 1H).
