Electric Literature of 63558-65-6, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 63558-65-6, name is 4-Chloro-5-iodopyrimidine, molecular formula is C4H2ClIN2, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.
Step 7: (R) 4-[(lR)-7-Chloroisochroman-l-yl]-5-methyl-2 hienyl]-(4-chloropyrimidin-5- yl)methanol and (S)-[4-[(lR)-7-Chloroisochroman-l-yl]-5-methyl-2-thienyl]-(4-chloropyrimidin- 5-yl)methanol [00710] A solution of 4-chloro-5-iodopyrimidine (7.05 g, 29.3 mmol) in THF (100 mL) was cooled at -78 C. To the solution was added 2.50 M of n-BuLi in hexane (23.4 mL, 58.6 mmol) at the same temperature. After stirring for 10 min, a solution of 4-[(lR)-7-chloroisochroman- l -yl]-5-rnethyl- thiophene-2-carbaldehyde (7.15 g, 24.4 mmol) in THF (28.6 mL) was added at -78 C, and the resulting mixture was stirred for 10 min at the same temperature. The reaction was quenched by addition of water and extracted with EtOAc. The combined organic layers were washed with brine, dried over Na2S04, filtered, and concentrated in vacuo. The residue was purified by silica gel column chromatography (0 to 50% EtOAc in hexane) to give 9.34 g (94%) of the title compound mixture. NMR (400 MHz, DMSO-d6) delta 8.99 (s, 1 H), 8.94 (d, J = 3.1 Hz, 1 H), 7.23 (d, J = 2.6 Hz, 2H), 6.67 (d, J = 4.6 Hz, 1 H), 6.61 (d, J = 6.9 Hz, 1 H), 6.53 (d, J = 5.5 Hz, 1 H), 6.02 (dd, J = 8.1 , 4.6 Hz, 1 H), 5.74 (s, 1 H), 4.1 1 – 4.04 (m, 1 H), 3.84 – 3.74 (m, 1 H), 3.02 – 2.92 (m, 1 H), 2.73 (d, J = 16.6 Hz, 1 H), 2.37 (s, 2H), 2.36 (s, 1 H).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 63558-65-6, 4-Chloro-5-iodopyrimidine.
