Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 1193-21-1, name is 4,6-Dichloropyrimidine. A new synthetic method of this compound is introduced below., Safety of 4,6-Dichloropyrimidine
Example 38; Preparation of 4-[6-(4-trifluoromethoxyphenyl)-pyrimidin-4-yl]-benzaldehyde Step 1. 4-Chloro-6-(4-trifluoromethoxy-phenyl)-pyrimidine was prepared by palladium-catalyzed arylation of 4,6-dichloropyrimidine and 4-trifluoromethoxyphenyl boronic acid. 1H NMR (400 MHz, CDCl3) delta 9.05 (s, 1H), 8.14 (d, J=9.8 Hz, 2H), 7.74 (m, 1H), 7.36 (d, J=8.4 Hz, 2H); EIMS 274 m/z (M+).
