Electric Literature of 6443-85-2, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.6443-85-2, name is 2-(Pyridin-3-yl)acetonitrile, molecular formula is C7H6N2, molecular weight is 118.14, as common compound, the synthetic route is as follows.
Example 1A trans-2-(3-Pyridyl)-3-(3,5-dichlorophenyl)-2-propenenitrile To a stirred solution of 400 g (2.3 mole) 3,5-dichlorobenzaldehyde in 11.4 liters absolute ethanol were added 283.5 g (2.4 mole) 3-pyridylacetonitrile and 720.9 g of K2 CO3. Within 2 minutes of the K2 CO3 addition, a solid precipitate formed. The reaction mixture was stirred about 2.5 hours. Water (22.9 liters) was added to the stirred reaction mixture. After stirring for 1 hour, the mixture was filtered and the filter cake was washed with water (10 liters), dried and recrystallized from isopropanol. Five hundred thirty four g (85% yield) of trans-2-(3-pyridyl)-3-(3,5-dichlorophenyl)-2-propenenitrile were obtained, m.p. 150-151 C.
The chemical industry reduces the impact on the environment during synthesis 6443-85-2, I believe this compound will play a more active role in future production and life.
