Synthetic Route of 939986-65-9, 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.939986-65-9, name is 6-Chloropyrimidine-4-carbonitrile, molecular formula is C5H2ClN3, molecular weight is 139.5425, as common compound, the synthetic route is as follows.
To a stirred solution of compound 3 (55 mg, 0.29 mmol) inN-methyl-2-pyrrolidone (5 mL) at RT, were added 6-chloropyrimidine-4-carbonitrile (60 mg, 0.43 mmol) and Cs2CO3 (189 mg, 0.58 mmol), and the mixture was stirred for 12 h. The reaction mixture was diluted with water (10 mL) and extracted with EtOAc (2 x 15 mL). The combined organic extracts were washed with brine (10 mL), dried over Na2SO4, filtered, and concentrated under reduced pressure. The crude was purified via trituration with n-pentane (2 x 2 mL) to afford compound 4 (55 mg, 65%) as pale brown solid. ?HNMR (500MHz, DMSO-d6): 8.85 (d, J 0.9 Hz, 1H), 8.00 (d, J= 0.9 Hz, 1H), 7.77 (d, J= 3.2 Hz, 1H), 7.56 (d, J 8.4 Hz, 1H), 7.23 (t, J 8.0 Hz, 1H), 6.95 (d, J= 7.5 Hz, 1H), 6.32 (d, J= 3.2 Hz, 1H), 5.86-5.78 (m, 1H), 5.05 (t, J 7.4 Hz, 2H), 4.95 (t, J= 6.7 Hz, 2H); LCMS Mass: 293.0 (M+1).
The chemical industry reduces the impact on the environment during synthesis 939986-65-9, I believe this compound will play a more active role in future production and life.
