Application of 7664-66-6, 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. 7664-66-6, name is 4-Isopropoxyaniline belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
Example 54: Preparation of 2-[l-(4-fluorophenyl)-3-[2-(4-methoxyphenyl)ethyl]-5- oxo-2-sulfanylideneimidazolidin-4-yl]-N-[4-(propan-2-yloxy)phenyl]acetamide. – EDCI (143 mg; 0.74 mmol; 1.5 eq), followed by HOBt (113 mg; 0.74 mmol; 1.5 eq), DIPEA (256 muU 1-49 mmol; 3 eq) and 4-(propan-2-yloxy)aniline (150 mg; 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 18 hours. Saturated ammonium chloride (20 mL) was added and the aqueous layer was extracted with ethyl acetate (3 x 25 mL). The combined organic layers were washed with saturated sodium chloride (3 x 20 mL), dried over sodium sulfate, filtered and concentrated to dryness. The crude was purified on silica gel using dichloromethane/ethyl acetate (95/5) as an eluent. After trituration in diethyl ether/ethanol, the title compound 2-[l-(4-fluorophenyl)-3-[2-(4- methoxyphenyl)ethyl]-5-oxo-2-sulfanylideneimidazolidin-4-yl]-N-[4-(propan-2- yloxy)phenyl]acetamide was obtained with 43% yield (114 mg) as a white solid. 1H- NMR (Acetone-d6): delta (ppm), 1.26 (d, 6H), 2.94 (m, 1H), 3.15 (m, 2H), 3.36 (m, 1H), 3.74 (s, 3H), 3.78 (m, 1H), 4.31 (m, 1H), 4.59 (m, 2H), 6.86 (d, 4H) , 7.25 (m, 4H), 7.48 (m, 4H), 9.32 (s, 1H); MS (ESI+): m/z = 535.9 [M+H]+ .
The synthetic route of 4-Isopropoxyaniline has been constantly updated, and we look forward to future research findings.
