1-Hydroxybenzotriazole → 2-(4-Chloro-phenyl)-3-hydroxy-N-[5-(7-isopropyl-7H-pyrrolo[2,3-d]pyrimidine-5-carbonyl)-pyridin-3-yl]-propionamide

온도

25 °C

2-(4-Chloro-phenyl)-3-hydroxy-propionic acid (570 mg, 2.84 mmol) (Preparation 244) was added to a solution of (5-Amino-pyridin-3-yl)-(7-isopropyl-7H-pyrrolo[2,3-d]pyrimidin-5-yl)-methanone (200 mg, 0.71 mmol) (Preparation 95) in THF (5 mL). Di-isopropyl ethylamine (0.64 mL, 3.56 mmol), EDCI.HCl (273 mg, 1.42 mmol) and HOBT (193 mg, 1.42 mmol) were added and the mixture was stirred at 25° C. for 48 hours. The reaction mixture was quenched with saturated aqueous sodium bicarbonate solution (2 mL) and extracted with ethyl acetate (3×15 mL). The combined organic layer was washed with water (5 mL), brine (5 mL), dried over sodium sulphate and evaporated in vacuo. The crude material was purified by preparative TLC (dichloromethane:methanol 93:7) to afford the title compound as a yellow solid in 3% yield, 10 mg.
