Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 29133-99-1, name is 4,6-Dichloro-2,5-diphenylpyrimidine. This compound has unique chemical properties. The synthetic route is as follows.
Under N2, to the solution of cinchonine (1.47 g, 5.0 mmol) and 4,6-dichloro-2,5-diphenylpyrimidine (1.51 g, 5.0 mmol) in PhMe (100 mL) was added powdered KOH (4.20 g, 75 mmol) portion wise. The suspension was heated to 90 C. for 10 mins and then refluxed for another 50 mins. Then the resulting mixture was cooled to room temperature and diluted with water (50 mL). The organic layer was separated. Next the aqueous layer was extracted with CH2Cl2 (50 mL×3). The combined organic extracts were washed with brine (100 mL), dried over Na2SO4 and concentrated under vacuum. The yellow residue was applied to column (CH2Cl2/MeOH=100/1 to 10/1) to afford C-S1 as a white solid (2.43 g, 87% yield).
