实验步骤: To a solution of 2-(4-hydroxy-2-(1H-pyrazol-1-yl)pyrimidin-5-yl)acetic acid, 12-d, (150 mg, 0.68 mmol) and HOBt (101.2 mg, 0.75 mmol) in DMF (5 ml) was added EDC.HCl (144 mg, 0.75 mmol) and DIEPA (264 mg, 2.05 mmol). The solution was stirred at room temperature for 5 mins before the addition of the chlorophenyl amine (0.75 mmol) (Sigma-Aldrich). The mixture was stirred at room temperature for 24 hours. The mixture was then diluted with water and extracted with ethyl acetate. The organic layer was concentrated under vacuum and the residue was purified by silica gel column or Prep-HPLC to give the final compound 12-1. 1H NMR (DMSO-d6, 300 MHz): δ 10.23 (s, 1H), 8.56 (d, 1H), 7.92 (s, 1H), 7.63 (d, 2H), 7.37 (d, 2H), 6.64 (s, 1H), 3.53 (s, 2H). (M+H)+=330.1.
