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. 144690-33-5, name is Ethyl 4-(2-hydroxypropan-2-yl)-2-propyl-1-((2′-(1-trityl-1H-tetrazol-5-yl)-[1,1′-biphenyl]-4-yl)methyl)-1H-imidazole-5-carboxylate belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. HPLC of Formula: C45H44N6O3
Example 2; The reaction part was charged with ethyl 4- (1-hydroxy-1-methylethyl) -2-propyl-1- {4- [2- (trityltetrazol-5-yl) phenyl] 22 g of 5-carboxylate (Formula 4), 3.1 g of sodium hydroxide and 90 mL of ethanol were added and the mixture was stirred at 20 to 25 C for 4 to 5 hours. When the reaction was completed, the reaction solution was concentrated. To the residue were added 50 mL of ethyl acetate and 50 mL of purified water. The mixture was stirred for 1 hour and then layered. The separated organic layer was washed twice with an aqueous solution containing 30 g of salt and 170 mL of purified water. 1 g of activated carbon and 20 g of anhydrous sodium sulfate were added to the organic layer, followed by stirring for 30 minutes to 1 hour, followed by filtration. The filtrate was concentrated under reduced pressure, and then methanol (65 mL) was added. The mixture was stirred for 3 hours and then filtered to obtain 4- (1-hydroxy-1-methylethyl) 5-yl) phenyl] phenyl} -methylimidazole-5-carboxylate (formula 5) 20.7g (yield 95%, purity 99.98%)
The synthetic route of 144690-33-5 has been constantly updated, and we look forward to future research findings.
