4-氯-2-(甲基硫代)嘧啶-5-甲腈 - Reference Information
| introduction | pyrimidine is a very important heterocyclic compound, which is widely used in the fields of medicine and pesticides. Because pyrimidine compounds have the advantages of high efficiency, low toxicity and unique mode of action, their molecular design, synthesis and biological activity research are still a very active field in the research of heterocyclic compounds. Pyrimidine derivatives are used as receptor tyrosine kinase inhibitors and are used in the treatment of cancer. 4-Chloro-2-methylthiopyrimidin-5-nitrile is a heterocyclic organic compound that can be used as a pharmaceutical intermediate. |
| Use | 4-chloro-2-methylthiopyrimidine-5-nitrile is an organic intermediate. It has been reported that 4-chloro-2-methylthiopyrimidin-5-nitrile can be used to prepare steroidal anti-androgen compounds. Pharmacological experiments have proved that these compounds have good anti-prostate cancer activity. |
| preparation | 2g(6.6mmol) of raw material 4-chloro-2-methylthiopyrimidine -5-carboxylate ethyl ester is dissolved in 10ml of anhydrous ethanol, 0.68g of NaOH solid and 10ml of water are added, and the temperature is heated to reflux. TLC showed complete response after 1h. Rotate and dry the ethanol, adjust the PH to 3 with 6N HCl, and a large amount of solid is precipitated. 1.69g of white crystal was obtained by suction filtration with 91.8% yield. |
