Adding a certain compound to certain chemical reactions, such as: 56621-89-7, 5-Amino-2-methoxypyrimidine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Application In Synthesis of 5-Amino-2-methoxypyrimidine, blongs to pyrimidines compound. Application In Synthesis of 5-Amino-2-methoxypyrimidine
Example 82: Preparation of2-[l-(4-fluorophenyl)-3-[2-(4-methoxyphenyl)ethyl]-5- oxo-2-mlfanylideneimid zolidin-4-yl]-N-{2-methoxypyrim TBTU (244 mg; 0.74 mmol; 1.5 eq) and DIPEA (170 mu 0.99 mmol; 2 eq) were added to a solution of 2-[l-(4-fluorophenyl)-3-[2-(4-methoxyphenyl)ethyl]-5-oxo-2- sulfanylideneimidazolidin-4-yl]acetic acid (1-21) (200 mg; 0.50 mmol; 1 eq) in anhydrous dioxane (8 mL). The reaction mixture was stirred at room temperature for 30 minutes. 2-Methoxypyrimidin-5-amine (124 mg; 0.99 mmol; 2 eq) was added and the reaction mixture was stirred at room temperature for 18 hours. Saturated ammonium chloride (20 mL) was added and the aqueous layer was extracted with ethyl acetate (2 x 30 mL). The combined organic layers were washed with saturated sodium chloride (1 x 20 mL), filtered and evaporated to dryness. The crude was purified on silica gel using dichloromethane/methanol (98/2) as an eluent. After trituration in diethyl ether, the title compound 2-[l-(4-fluorophenyl)-3-[2-(4- methoxyphenyl)ethyl]-5-oxo-2-sulfanylideneimidazolidin-4-yl]-N-(2- methoxypyrimidin-5-yl)acetamide was obtained in 25% yield (79 mg) as a white solid. 1H-NMR (Acetone-d6): delta (ppm) delta 2.96 (m, 1H), 3.09 (m, 1H), 3.24 (m, 1H), 3.43 (m, 1H), 3.75 (s, 3H), 3.78 (m, 1H), 3.92 (s, 3H), 4.30 (m, 1H), 4.65 (s, 1H), 6.86 (m, 2H), 7.25 (m, 4H), 7.45 (m, 2H), 8.75 (m, 2H) 9.62 (m, 1H); MS (ESI+): m/z = 509.9 [M+H]+ .
