In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 147118-37-4, name is N-(4-(4-Fluorophenyl)-5-formyl-6-isopropylpyrimidin-2-yl)-N-methylmethanesulfonamide, the common compound, a new synthetic route is introduced below. Application In Synthesis of N-(4-(4-Fluorophenyl)-5-formyl-6-isopropylpyrimidin-2-yl)-N-methylmethanesulfonamide
Example 6b Using NaHMDS N-(4-(4-fluorophenyl)-5-formyl-6-isopropylpyrimidin-2-yl)-N-methylmethanesulfonamide (0.5 g, 1.4 mmol) and 2-((4 ,6S)-6-((benzo[d]thiazol-2-ylsulfonyl)methyl)-2,2-dimethyl- 1 ,3-dioxan-4-yl)acetate te/f-butyl ester (0.7 g, 1.6 mmol) were added to 10 mL of dry THF. After stirring for 10 min at 20C, the reaction mixture was cooled to -70C. At this temperature 1.9 mL of NaHMDS solution (1 M in THF, total 3.8 mmol) was added in 60 min keeping the temperature between -70 and -75C. When dosing was completed, the temperature of the reaction mixture was allowed to increase to -10C. After stirring at this temperature for 1 h, the reaction was quenched with 10% aqueous NaHC03 (5 mL). The phases were separated. The aqueous layer was extracted with 2 x 20 mL of ethyl acetate. The combined organic phases were washed with 5% aqueous Na2C03 and concentrated under vacuum. H PLC analysis indicated an E to Z ratio of >99: 1 . The residue was crystallized from methanol to give 2-((4f?,6S)-6-((E)-2-(4-(4-fluorophenyl)-6- isopropyl-2-(N-methylmethylsulfonamido) pyrimidin-5-yl)vinyl)-2,2-dimethyl-1 ,3-dioxan- 4-yl)acetate, te/f-butyl ester as a solid (0.52 g, 0.9 mmol, 64% yield).
The synthetic route of 147118-37-4 has been constantly updated, and we look forward to future research findings.
