実験手順

4-Chlorophenylisocyanate (19.0 mg, 0.124 mmol) was added to a solution of 1-{2-[4-amino-2-(4-chloro-2-methyl-2H-pyrazol-3-yl)-phenoxy]-ethyl}-azetidin-3-ol (40.0 mg, 0.124 mmol) in dichloromethane (2.0 mL) and DMF (0.1 mL), and the mixture stirred at room temperature overnight. The solution was concentrated and purified by RP-HPLC. The collected fractions were concentrated and 12% sodium hydroxide (aq) (0.2 mL) was added to give pH 9. The solution was extracted into ethyl acetate and the organic layer was dried over sodium sulfate, filtered, and evaporated to dryness to give a white solid (28 mg, 47%). LCMS m/z (%)=476 (M+H 35Cl, 100), 478 (M+H 37Cl, 67). 1H NMR (400 MHz, DMSO-d6) δ: 8.81 (bs, 1H), 8.71 (bs, 1H), 7.60 (s, 1H), 7.53-7.50 (m, 11H), 7.47 (d, J=2.08 Hz, 1H), 7.46 (d, J=2.10 Hz, 1H), 7.36 (d, J=2.71 Hz, 1H), 7.32 (d, J=2.11 Hz, 1H), 7.30 (d, J=2.04 Hz, 1H), 7.11 (d, J=9.06 Hz, 1H), 5.19 (d, J=8.00 Hz, 1H), 4.10-4.00 (m, 1H), 3.99-3.85 (m, 2H), 3.65 (s, 311), 3.40-3.30 (m, 2H), 2.70-2.55 (m, 4H).
