Hazard Information | Back Directory | [Uses]
2-Chloro-7-cyclopentyl-N,N-dimethyl-H-pyrrolo[2,3-d]pyrimidine-6-carboxamide belongs to pyrimidine derivatives,it is used in the synthesis of ribociclib intermediates. | [Synthesis]
To a three-necked flask was added 2-chloro-7-cyclopentyl-7H-pyrrolo[2,3-D]pyrimidine-6-carboxylic acid (26.57 g, 100 mmol) and N,N-dimethylformamide (133 mL), and the mixture was cooled to 0-5 °C under stirring. EDCI (23.00 g, 120 mmol) and a tetrahydrofuran solution of dimethylamine (2.0 M, 75 mL, 150 mmol) were then added. Triethylamine (20.24 g, 200 mmol) was added dropwise and the mixture was stirred at 20-25 °C for 6-8 hours. After completion of the reaction, the reaction mixture was extracted three times with ethyl acetate (133 mL) and the organic phases were combined. The organic phase was sequentially washed twice with water and once with brine (133 mL), dried with anhydrous sodium sulfate and concentrated. Finally, the target product 2-chloro-7-cyclopentyl-N,N-dimethyl-7H-pyrrolo[2,3-d]pyrimidine-6-carboxamide (26.93 g, 92% yield) was purified by column chromatography in a mixed solvent of dichloromethane and methanol. | [References]
