Procedure

To a solution of 2-benzo[d]isothiazol-7-yl-4-(1-piperidin-4-yl-1H-pyrazol-4-yl)-furo[2,3-c]pyridin-7-ylamine (20.8 mg, 0.05 mmol) in DMF (0.5 mL) was added diisopropylethylamine (0.05 mL, 6.5 mmol) and isobutyl isocyanate (0.06 mmol). The resulting solution stirred at room temperature overnight. The mixture was concentrated and then purified by MDP to afford the title compound as an off-white solid. 1H NMR (400 MHz, CD3OD): δ 9.51 (s, 1H), 9.12 (d, J=1.5 Hz, 1H), 8.84 (d, J=7.3 Hz, 1H), 8.72 (d, J=7.3 Hz, 1H), 8.35 (s, 1H), 8.07 (s, 1H), 7.92 (s, 1H), 7.88 (s, 1H), 4.53 (m, 1H), 3.03 (m, 4H), 2.18 (m, 2H), 2.06 (m, 4H), 1.83 (m, 1H), 1.76 (d, J=5.8 Hz, 6H); MS (ESI): MS (ESI): 516.64 [M+H]+; HPLC tR=0.86 min (HPLC: Analytical—2 min).
